It's just that it look pretty ridiculous to brag about releasing "first party games" (bought third party studio/games if the term "stolen" makes you uncomfortable) when your competitors have been creating first party games since forever.
Again, none of this has any relevance. Nobody at the consumer level cares how the omelette is made. You think anyone who talks about Sony's lineup for this year cares that FFXVI was a bought exclusive or Spiderman 2 comes from a purchased studio, with paid exclusivity on a popular, mainstream IP?
It's business. Nothing more. And certainly no issue for the end user.
Claiming Microsoft's first party studios don't make first party games is weird as hell. But par for the course with this thread anyway.
