Sony didn't move. This sounds like YOU feel emotionally about this situation and are trying to cast blame now, and I don't understand why that has to be in the conversation at all. Like, look. Maybe just, the space they were in wasn't where they needed to be, so they left. That's fine. There is no blame here.
Like, we can be accurate about what happened without it indicting thatgamecompany. Sony made a space, and invited thatgamecompany into that space. Thatgamecompany attempted to build something there, and while it was successful, it wasn't successful enough, so they left that space behind, because that's what they needed to do. You're still like, trying to tie "leave behind" to this idea of fault as if that is inherent, and it isn't; like...we don't need to ya know? It can be purely descriptive here.
The space they were wasn't good enough to support them, so they left it behind. That means leaving some audience behind, which sucks, but that's the way the world spins.
I don't know why you seem so caught on the idea of trying to tie "leave behind" to "at fault." Obviously there can be some negativity here, but like, negativity and downsides to a decision don't make that decision bad or the person making them a bad person. Thatgamecompany had to leave some of their audience behind. Sucks for the audience, but it was the right decision for thatgamecompany. We don't need to like, asign blame to thatgamecompany, or the audience, or sony. It is what it is.
