TROS suggests that Palpatine does it with Kylo, but not with Rey (for some unknown reason). When he says, "I am every voice . . . you have *ever* heard . . . inside your head," does that not suggest an ability to do exactly what you're saying shouldn't happen in SW?
Isn't that why we now have something like this in canon?
You keep making it seem like I'm drawing inferences erroneously, and making stuff up, just to bash this movie. Then explain to me why LFL is doubling down on some of the same basic conclusions that I took away from watching it. In those panels above, you see Snoke and Palpatine having equal access to what Ben Solo is doing. You can dismiss the comics all you want, but you know better than to think these writers didn't genuinely draw similar conclusions from what they saw in TROS.
If you want to take Palpatine's "I am every voice . . ." dialogue far from literally, you're certainly entitled to. But what is it that makes you think that my more literal interpretation (which LFL's own writers may end up canonizing) is baseless or invalid?
For me, you can't have Force ghosts establish an inclination to guide the living Jedi in the OT during perilous times and then bring the same situation back 30 years later in the ST and have them suddenly doing the opposite. Anakin's spirit knowing Palpatine is behind all this, and choosing not to guide his son and daughter so as to prevent even more tragedy than the PT and OT creates a cognitive dissonance for me.
Having Luke cut himself off from the Force in TLJ was one of my favorite decisions (among many problem-corrective ones that most people totally overlook) because it gave a reason for Luke not being able to get guidance from Anakin, Obi-Wan, and Yoda. And as soon as he taps back into the Force, he gets guidance from Yoda. That makes logical sense with what Force ghosts context was established in the OT.
But to believe that Anakin wouldn't know Palpatine's involvement, and wouldn't guide his kids by making them aware of the truth, is something that doesn't sit well with me because it doesn't seem consistent. It's not a huge deal, but it's just one of many things.
