While I dislike Konami's move towards pachinko and mobile I can't blame them for it, they are a business and it makes money. I am also inclined to believe Kojima is not good at project management. All signs indicate he was over budget and late on delivering. He had already had what, 80 million dollars and five years? So yeah, I think the "Fuck Konami" train is a bit much, but it does suck that they are moving away from AAA development. To say nothing of Konami's allegedly shitty work environment.
We will see if this works out, it just may be that Kojima needs someone to hold him accountable which may not happen now that he has his own studio. Plus, notable game devs going off to start their own studio has a checkered past.
