I can tell you why, because the mainstream media and gaming community websites allowed them to be fanboys, and become the useless scum that they are, keep in mind I think all of us when we were young had a preference, I did at one point and it was Nintendo but for some reason, I grew out of it and liked all. Now I'm not saying having a console preference along with PC is bad. But when you are spewing out your toxicity in the gaming community and starting internet fights on who's better. That's where I draw the line and I also blame companies to allow such behavior. Again it's okay to have a preference, nothing wrong with that all, if you like Xbox, Nintendo, PlayStation, PC, and yes even cloud gaming, oh and let me not forget about mobile gaming. That's okay, but again if you start being toxic and spewing out your fanboyism that's when it becomes a big problem. Also keep in mind, that people who still do this spread hate and toxicity on the gaming community are people in their 30s to 40s still fighting over a company who clearly doesn't give a fuck about you or your feelings. What they want is your money, they are not your friend.
That's my take on this.
