It's likely to forever remain a niche for that kind of content only. What reasonable person would say: "I know, I'll host my video on that website which opens with a list of conspiracy videos and has antisemitism promoted in the sidebar next to my content/face." (And even more - which popular company would do that?)
If there are enough benefits to the platform and semi-popular (likeable) Youtubers switch to it, the problem should resolve itself after a few days. Luckily antisemites etc. are a minority of the population and can be easily outnumbered.
I think the question is if the risk of very loose association with that content is higher than the risk of loosing out on revenue by arbitrary decisions from Youtube.
Given what happend over the last year with the Adpocalypse, most of them realized that being at the whim of Youtube is a real risk, and are now looking to diverisfy their income streams (see growth of Patreon).
Conspiracy videos are important. Think "Collateral damage" videos showing US war crimes....good luck hosting that on YouTube.
Now, if you're talking conspiracy theories, that's totally different, and still not a problem, for many who believe in free expression, regardless if they're interested or not.

Well people still advertise on Reddit next to T_D and other nutjob subreddits. Unfortunately.
Note that reddit devs are trying hard to hide these controversial subreddits. You won't see them if you go to https://www.reddit.com/ for instance. That's partly why they introduced the "popular" meta-subreddit a while ago. Reddit is pretty advertiser friendly, hence famous people making AMAs to promote something, official or semi-official subreddits for some video games etc... If you want to see the controversial content you have to look for it, for the most part. I consider it very hypocritical of reddit admins to handle things that way but it seems to work decently for them so far.
Contrast that with something like https://voat.co/ for instance. At the moment I can see only one (1) post in the entire front page that's not alt-right politics. Special mention to the highly upvoted "If women have the right to terminate unwanted life because it's in their body, do we have the right to terminate unwanted illegals because they're inside our country?". I don't expect most advertisers will want to touch that with a one parsec pole.
Reddit could ban that entire crack den of T_D and friends.
Let them go to voat, it was specifically founded for the alt-right, same as gab.ai as a Nazi twitter clone. They're all alone out there and don't have any influence anymore... the problem with T_D specifically is that their users lesk out to other, normal subreddit and spew their stuff there. Ban the subreddit, ban all the top commenters/submissions, their admins and forward the dirty stuff to law enforcement.

Except it wasn't. It simply experienced more and more waves of users from banned subreddits (which were mainly alt-right related ones) coming in and eventually making an hard right turn on the main website culture, driving out most existing center/left users. It did serve me as a lesson on what external influences can do to existing communities tho.
