I think a lot of the reasons Sony gets more flack than others is because the fan base of Sony defends Sony to the point where they don't think Sony does anything wrong,ever. But the fact at the end of the day is that all companies downgrade their games, Nintendo,Microsoft,Sony,third parties(im looking at you Ubisoft). It's common place for this. So its wrong for Sony to only be targeted for this and that isn't really fair. But it is what it is, best to just ignore all the noise and just enjoy the games were given.
Nintendo and Microsoft fan bases do exactly the same thing, as does almost any other fan base.
