Uhm, you know the reason. For most part of the existence of the company. Xbox was never really a match for PS. PS sells tons of games via retail and PS store. Xbox abandoned their consoles very quick without any support in the past. They haven't released any worthwhile game for a long long time, and still can't manage to launch their main franchise as a whole game. This year ended again with 2 games we all know already by now.
The only one that needed big changes is MS and not Sony. The last one isn't in a hurry and then again, Jim already said last year that they had info about a "gamepass" compatitor, but couldn't say more. Atm, you are only guessing nothing more then that.
Who cares if they rename it. The PS+ service is already a better then Gold and PSNow in general. Combine that with everything PSNow and overhaul it with new hardware in the racks and PS5 games/streaming, then they are done imo. The only thing they need to do is to release it on other devices or tv's again.
Again, this has all to do with Xbox that was just a pile of shit for 2 generations. They needed some big changes.
I don't know what you want to say here, but i guess you still think Sony can't because "tHeY dOn'T hAvE tHeIrE oWn dAtAcEnTeRs".
Os has nothing to do with all of this. It only benefits the MS store or development for their software but nothing else. Sony can have their service on Windows like Steam, Epic Store or whatever. They don't compete with Windows and that also makes no sense.
Again...what is your point? PlayStation can't and Xbox is the only one that can? Your arguments won't age well...
