Well that's one of the stupidest arguments i have ever seen.
Sony's entire financial positioning isn't dependent on them blocking crossplay either. It literally doesn't benefit them in any way whatsoever. It's, again, idenfensible garbage.
We already know why Sony doesn't want crossplay. Why open up your platform to the possibility of your competitor being able to preach to your customer? Business wise it makes sense. However, you have guys like yourself who can't see that. For the record, I never once said I supported the stance that Sony is currently adopting. I just found it interesting that people are choosing to die on this hill for something that is purely a business decision and acting like Sony is personally going into your home and mollywhopping you.
