Gamepass is a direct competitor to Nintendo, services like Youtube, Netflix or Amazon Prime are not. Not really the same.
Nintendo isn't going to get bad press either way.
Maybe you should ask yourself what Nintendo stands to gain from having Netflix and Amazon Prime on their console.
More services and flexibility for their hardware? I get that the focus of the Switch is gaming, which is what it should be, but I'm somewhat annoyed with the lack of QoL elements and services that have become ubiquitous on it. Again, it's not a big deal, but consoles really should have more features than their predecessors, not less.
