How do you comfortably feed Sony while they pay to take content from others?

I don't understand the whole "we have exclusives" parade. Don't you want all gamers to enjoy all games? I'm primarily on Xbox, and whenever we get a cool game I think, "it would be nice to play this with people on PS4". But instead there is this childish war about whether or not Xbox has enough exclusives and Sony is superior for all their exclusives. I just don't get it. I can't justify being happy that another platform is deprived of a game or content. Like Destiny 1, where Xbox just got the exclusive PS4 content. That tells me that Destiny doesn't give a shit about me. Why would I be happy that somebody else who pays the same as me, gets more content or gets it early? So why do you like this trend in the industry? I know it's enjoyed here. Almost every Xbox One X post on here has a comment about Microsoft not having enough exclusive games, so it's clear you guys love it.

Edit: I get it now. There's a lot more going on than just companies wanting to deprive others of games. They're more so looking for great games to be made for their console and they often pay for that to happen. And since they pay for it to happen, they get to have it as an exclusive. Thanks for the explanation.
