Dont know why you are getting annoyed at paying exactly the same price for the same game
Simple, we don't have to.
There's a reason Console games cost more, it's because to attract customers and be competitive, the actual Console is sold at a loss to make it cheap, where they actually make their money is the royalties or license fees that get added to any game or app that is released for their platform.
But nobody owns the PC platform, so nobody can collect royalties for games released on the platform, hence the games are a bit cheaper.
So when buying a PC game at console cost, you are basically paying a fee you don't have to, and you get nothing in return for it (on the Console, atleast it ment you got the machine cheaper, but i doubt Activision helped you pay for your gaming rig..), and the publisher just pockets the dough, it's just greed really, and people usually aren't enthusiastic about parting with their money to satiesfy others greed..
