A reply to you makes the unsubstantiated claim that YouTube is a profit-seeking company. They ignore the fact that, no, YouTube has not operated as a profit-seeking company. The reason YouTube is, and will remain, the pre-eminent video platform is because it was run at a profound loss for over a decade, losing hundreds of millions of dollars at a clip, for no reason other than to totally suppress competition. Framing them as some kind of capitalist company is genuinely false.
If you wish to build a competitor to YouTube, your first task is to secure a billion dollars or so to build a competitive infrastructure with investors who are prepared to lose money on its operation for no less than a decade and quite possibly forever (or until Google goes bankrupt).
