I remember the report that when Microsoft initially planned to enter the console space they wanted to recruit Miyamoto with 10x salary. The proposal was outright rejected because he cannot do anything meaningful without the team and culture he had been building over decades. In the creative industry, teams and cultures are (almost) everything.

Nintendo will unlikely keep its team and culture when it's acquired by some random US big techs. Japan and US just have so different corporate cultures at their fundamental level. Think about a hypothetical scenario; another big economical crisis is looming and Satya mandated Nintendo to cut 5~10% of its HQ employees. Would Nintendo keep its unique culture after its first ever lay-off? I don't think so.
