To me it only shows that companies hurt their sales if they agree to exclusive marketing deals. I don't think that PS4 sales would be lower if they would also mention other console in the ads but Xbox and maybe PC sales would be higher. Well, PC sales died pretty quick and player count on Steam looks horrible for the game, seems like they didn't do themselves a favour with their "famous" PC release.
If some average Joe doesn't even know about this game on his console or if he doesn't think that it's a "must" to have this game because he didn't see advertisement for it on his console 50x in a row, he won't buy the game. That's how "average gamers" think.
Telling owners on other consoles or PC that they get a version with less content for the same price does also not really sound convincing as owner of these systems to be honest.
