Why do PC gamers rage about Sunset/MCC/Forza?

i looked at some youtube videos and a lot of PC gamers were flipping out about people playing MCC in comments trying to bash the game (since it don't come out on pc/ps4)

and they also flipped out over pewdie pie playing sunset overdrive there very mad about any exclusives for xb1 ive noticed and i saw a few begging for forza as well

why can't they just get an xb1 if they have pc/ps4 whats one more system to them?

But why do you care so much about other people?

This topic is not really suited to the Xbox board.

I suggest maybe taking a different view on it and then maybe discuss it on System Wars. However, I feel with this as an opening post you may face a lock there as well, I would say try phrasing the question different and use the Xbox as an example (alongside the other systems and games).

Thanks.
