Honestly, if anyone could actually run a successful YouTube alternative that could actually compete with Google's mess, it probably would be Mind Geek.
The main issue with any YouTube competitor is that YouTube has always ran at a loss and is mainly propped up by Google and YouTube was one of those things that was in the right place and right time when it debuted in 2005.
There wasn't any video site like that before (except maybe some porn sites) and it caught on in popularity. Also, consider the era that "Classic YouTube" was in. 2005-2008 was peak Web 1.5 and internet culture was going mainstream, yet had not been fully sanitized and bland like Web 2.0 in the 2010's. A lot of people, especially Millennial teens and Zoomer kids flocked to it since it was different from cable TV and other normie fare.
Google saw a lot of opportunity in this and bought YouTube. I'm not sure if they were expecting to make it profitable or if they always intended it to be a loss leader for advertisers, but they struck the iron while it was still red hot.
A lot of the other competitors like Blip TV, Metacafe, or Dailymotion either went completely under or languished in utter obscurity for the most part.
The only reason why Dailymotion and Bitchute even continue to exist is because YouTube is growing more draconian in their policies every passing moment it seems. Hell, I'm surprised VidLii even exists at all aside from the format being a clone of classic late 2000's YouTube.
A YouTube competitor requires a lot of infrastructure just to function and even more upkeep to make it actually relevant and nobody can do it without already making a fuckton of money from other enterprises. YouTube is largely propped up by Google's properties that are actually profitable and even then, it's such a money sink that they have to cram it full of commercials more than ever before.
Mind Geek already makes a lot of money from Pornhub and countless other porn sites, and given their particular line of business, they know how difficult it is to work with payment processors and have already figured a way around that so they can be profitable.
If they made a work-safe YouTube competitor, then Google would face some real competition on that front since it will be a lot harder to squash it than some no-name ghost town like Dailymotion.
