Fair enough. I'd be lying if I said that I'm perfectly fine with Yoda's ghost summoning lightning. I'm not. It's not a big enough deal to bother me (Luke tossing the lightsaber bothers me WAY more). As most of us do with movies that we largely appreciate a great deal, I forgive the things I object to in TLJ in favor of embracing everything that I love about it.
Momma always said that in life, we win not by fighting what we hate, but embracing what we love.
As far as the Force ghost element, though: if one accepts how Lucas defines them (as I do, and you don't), Force ghosts are the result of a learned Jedi skill. On screen in ROTS, this point becomes indisputable. Therefore, what Yoda does in TLJ has a logical basis. Force ghosts have more than just consciousness; they have a "presence" that is manifested by that Jedi's mastery of the Force. Felling a tree is . . . kinda, sorta acceptable.
Again, I always have a hard time incorporating PT stuff into this kind of OT lore conversation because so much PT stuff was not only so wrong, but forgettable (seriously, who dwells on midichlorians?.) So very little of it entered the zeitgeist and our collective psyche the way so very much of the OT did.
Kylo's line about "the effort would kill you" *is* a reference to the type of projection that Luke does. When Kylo is trying to figure out what the hell is going on as he keeps seeing Rey in his environment, his first instinct is that she must be using Force projection (the same type that Luke uses later). When he dismisses that possibility, it's because the effort to project herself that way would kill her.
The Force Skype stuff was . . . well, as Kylo put it: "this is something else." The hint RJ dropped was intended to preface what we would later see happen to Luke. The bit of Kylo dialogue set that lethal consequences rule/parameter. You can criticize the lack of subtlety, but I don't think it needed to be any more subtle or clever. If you Force project yourself, as Rey appeared at first to be doing (and Luke later *did* do), the effort ends up killing you. That keeps it from being a perpetual go-to "cheat" for the Jedi. Simple.
It's tricky the way you phrased that.
I've yet to encounter anything that explains how force projection actually works - even the basics. Like can you do it - at all - without dying? Or is the length of the experience that kills you (as Wookiepedia seems to coyly suggest,) and if you do it in shorter bursts you can use it as an actual skill? Did Luke KNOW he was going to die by doing it in TLJ? If so, did he consider other options before committing suicide? Why didn't he do it faster in TLJ to save himself? These are hugely important questions: it's hard to judge Luke's actions without knowing the answers (ie he's a total idiot if the length of experience does indeed kill you).
If this:
"Such an ability, while very powerful, nonetheless had severe consequences when utilized: prolonged use of the ability would result in the user's death." (from Wookiepedia
...is true, then WHY would Luke sit and have a nice long chat with Leia? Like his life is draining way with "prolonged" use, so why do that? Why not tell Leia the plan, get out there to Kylo, do the distracton so people can get away and pooof - he's gone. And STILL ALIVE.
This is what I mean about "rules" for some of this stuff in TLJ - for force projection, there are none that they have been able to concoct that even remotely explain what we see onscreen.
To be clear though - I am NOT saying that force projection couldn't work as a Jedi power, I'm saying as presented in TLJ it's a total muddle that makes it impossible to judge what Luke actually does (in his final act!.)
I'm really glad that you recognize the difference between Snoke's Force Skype deal and Luke's projection. Some fans confuse the two as being the same thing when voicing their objections, and it has frustrated me repeatedly. They're actually two entirely different things, and I think you nailed the distinction.
Yeah, other than some inherent cheese in the scenes ("put on a towel"?) the force texting thing I don't have any great problem with - as I mentioned, it's really no different than Luke/Vader in ESB and more crucially, the cut opening scene of ROTJ.
I disagree that that alone betrays the the OT concept of Force ghosts. There's no hard and fast universal law of ghosts that TLJ betrayed. There are tons of stories and movies where ghosts can interact with the physical world. Mostly horror films of course but not always; Valeria in Conan the Barbarian and Patrick Swayze in Ghost are two obvious examples of good ghosts directly interfering with bad guys to help the good. So Yoda nuking the tree in and of itself isn't a huge deal. Obviously Lucas was toying with such interactions all the way back during the writing of ROTJ.
The problem I see it is having Jedi ghosts interacting with the physical world seemingly without rules or limitations. Yoda doing it 35 years later really begs the question as to why he wasn't doing it all the time. Compared to say Valeria who we can assume simply appeared as a one time thing to fulfill a very specific promise she made in life.
Oh, I have no doubt that ghosts in other movies interact with the physical world, hey: slimer and the hot dogs! It's just there was no precedent for it with force ghosts in the OT, even though there were SO many opportunities where it could (and *SHOULD*) have happened - but didn't. Again, that's six hours of story over three movies shot over a 6 year period.

As Wor-gar says - force ghost (or earlier, force projecting) Yoda takes out Palps and Vader and no one has to die!
This is a problem that haunts so much about TLJ: Holdo manuever, force projection, force ghosts destroying stuff. Why did none of this ever happened before. I just don't buy all this "they didn't have a big enough spacecraft" or "nobody ever thought of it before" or "in a thousand generations, no Jedi ever achieved this before" or "there was this book that Luke read (in an OT universe that has no books)- it all feels way too convenient, and in a backhanded way, reduces the OT a bit by making the various OT entities idiots for not either knowing about it or thinking of it. It seems to betray the DESPERATION that permeates the OT.
Do you mean "what happened to the 'I cannot interfere' rule" in terms of Yoda calling lightning onto a tree?
If so, I suppose this would become a matter of semantics regarding what does it mean to "interfere." Was Kenobi already interfering by telling Luke to go to Dagobah for training? Was he interfering by persuading Yoda to train Luke? Or by telling Luke the details about Leia? I don't think any of those things qualify as "interfering" in the way Obi-Wan meant it.
To me, burning down a tree that no longer had any
sacred books in it doesn't amount to interfering in that way either. It'd be a bit like objecting if Obi-Wan had cracked the log he sat on. Who cares?
Yeeeahhh... about those sacred books, in the universe where no book has ever been seen, nor pens, nor paper... like there was a pre-OT paper apocalypse? Empire was into saving trees? That's another super-weird TLJ thing. And they are such tiny, unimpressive looking books too. Like the sacred Jedi pamphletts
