Depends what kinda players you are talking to. Xbox is a major thing where I live and everyone has one (I used to but then got the PS5). Playstation gets hard dissed around here. But online I have seen a lot of hate for Xbox.

It’s alright to have some friendly competition between consoles because that is what inspires the other to thrive and continue. Players are only hostile because they like to defend what their favourite is, companies like Xbox & Playstation need hardcore (and sadly hostile) fans because although they are aggressive, they are loyal. They will buy your new products and never buy the rivalling console. Once you lose your hostile & protective fanbase, that is when you need to worry.

So, in short, that is why the behaviour is still tolerated by games companies & why players are hostile to players from other consoles: loyalty.
