For what it's worth it's important to mention that I believe in what InArt's trying to achieve and am willing to support it, lest my point present as unilateral and I get martyred as a Hot Toys shill.
Obviously you and I are not going to agree here, but disingenuous it is not...perhaps hyperbolic but nevertheless rooted in consistent observations. Hot Toys has faults that are undoubtedly worthy of critique, and InArt's presence has given many people a new perspective on which to leverage those qualms. Despite that, you'd have to willingly turn a blind eye to the rapid spikes in vitriol driven towards the brand which has fundamentally paved the current landscape. When critique devolves to a point of jousting statements likening Hot Toys to Hasbro, it's not discussion anymore, it's pedantic. From that spirals a strange attestation that InArt wouldn't commit those sins, but HT does and so on. It's bizarre tribalism that makes for boring dialogue. If I wanted that, I'd turn on the news.
While sure, HT has a bigger footprint as you said, I think holding both brands to the same degree of FAIR scrutiny is appropriate. Especially when the newcomer promotes themselves as next-level premium, and subsequently charges the prices that they do.
Honestly the first place I've seen general apathy to an InArt release is Superman, to a degree which surprised me. In my eyes it's a significant upgrade from what has preceded it. Interestingly, just like this Wanda, the sculpt is rather unexpressive. Through through that thread there's just as much dialogue about the neutrality being preferable as it is a detractor, but here it's the presiding downside. Comparably, no one's calling InArt incompetent or lazy because of it. Even the Pennywise collar is being framed in the light of a misstep rather than ignorance.
Scarlett Witch is the new Black Widow for them, is she not? Black Widow had been their best selling figure (self reported by them at that). I think as long as the Artesian line exists as a unit-limited offering, it's not a huge ordeal. The people who are willing to buy three Scarlett Witch figures are the ones who are going to make every effort to get the next best one. It was the same case with the Joker, the people who wanted that edition were going to double down on trying to buy their umpteenth iteration of the character regardless.
