As a content consumer … none of those “alternatives” are alternatives to youtube.

They all immediately take you to a “how to buy hosting on our platform, and why our platform is good for hosting” pages. Rather than just taking you to the hosted content. So as a consumer, I now need to work out how to consume the content there. And … I ain’t gonna bother.

youtube.com the content is right there.

Youtube is a platform for consumers, that creators have to work for.
