Even though some high profile civil libertarian and free speech advocates like Glenn Greenwald and Zaid Jilani have chosen Rumble as home, YouTube is still lights years ahead. But if they continue to censor, alternative free speech platform will emerge.

Censorship advocates always get hit by the divine justice boomerang.
Beyond that there are some folks with some free speech ideals but even that devolves into "anything goes" and they turn a blind eye to the results because it is messy / unpleasant.
...but at the same time anyone who deviates from progressive orthodoxy in any way will be labeled alt-right.
So in addition to the hyper-toxic folks, you will get people looking for a platform allowing debate and a broad range of ideas.
The stimulating nature of extremism makes it really hard for a new platform to be pro-"sensible free speech".
It's nice to see that something you disagree with strongly, like alt-right content, can be labeled hyper-toxic and not be downvoted into oblivion. It is encouraging that HN as a platform can tolerate a strong opinion without retaliating.
That's the rub: Whenever a new platform starts up, marketing itself as the "free speech alternative" to some big, mainstream platform, what always ends up happening is the new platform's user base consists entirely of people who got kicked off the mainstream platform--leading to all the toxicity and problems noted in this sub-thread. You need to be more than a place where the cast-offs from mainstream sites hang out. You need to bring the mainstream to your platform too.
Not to claim that Brand can't be annoying, but he's not alt-right and I can't imagine them both occupying the same space.
Which is all fine and good until people start filing copyright claims, lawyering up, withdrawing adverts, and cancelling subscriptions. Not to mention the possibility of governments intervening.
Sooner or later regulation comes, whether that's directly, or indirectly via market pressures.
(Note that this isn't necessarily a bad thing - or a good thing, for that matter - just a thing. An example where it might be seen as more positive for, say, a government intervention to occur is Facebook/Meta. I'm certainly losing patience with Mark Zuckerberg's indifference to the individual and societal damage his platforms are causing.)
