Most 3rd party deals are only good for the companies involved and not the gamer as most of the time Sony/MS are just paying to delay game/DLC from getting to its rival (sometimes not at all - SFVI)
Both companies did it last gen, MS more because they had the market share. Some people complained. Both companies doing it this gen, Sony more because they have the market share. Some people complained. It's pretty much the same.
People complain about everything no matter what but what you should do super is not class xbox fans as one and PS fans as one. If you want to prove contradiction, you will have to show cases where the same person/website were against/for it but then change their mind when it worked against/for their favor. Or we can work with your logic, every time we see an xbox fan say something that's against what you believe we'll call them out for contradiction because surely you all think as one.
