There are legitimate criticisms to be had about the recent Final Fantasy games and about Square Enix as a whole, but I think much of the unbridled seething hate you hear hurled toward them these days is the simple fact that they're one of the big guys now. They're reviled for most of the same reasons Electronic Arts, Ubisoft, Activision, etc. are. They're huge and wield way too much publishing power over way too many beloved/once beloved franchises and the way they've been handling them in recent years (particularly in regard to their love for mobile and microtransations) is questionable.
