There isn’t a claim being made that all videos showing circumvention of the Microsoft account requirement for Windows 11 installation are being taken down. Only some of them. You saying “people will just believe anything that fits their worldview” sounds like you’re asserting that no takedowns are occurring. Thank you for clarifying that this is not actually your position.

The likelihood is that that this is being done automatically by youtube’s AI, rather than because of requests by Microsoft. I think the real problem illustrated here is the lack of transparency when Youtube issues a takedown. An initial glance at Youtube’s Community Guidelines doesn’t seem to indicate a criterion by which a takedown would be automatically issued for such content, but I wonder if they’re starting to automatically flag anything that might be considered circumvention guides. Yet another reason to stop using Youtube.
