You didn't answer the question - Do you want someone to regulate them?

I didn't answer the question because it was a non-sequitur and it was obvious the question was being asked in bad faith to trip me up, like a cop who asks how many drinks you had after you just told him you hadn't had anything to drink.

I don't have a strong opinion on the matter. If someone were to do a good job regulating them and make the situation better I'd approve. If someone were to do a bad job and make things worse I'd disapprove.

So your solution is for someone else to come up with a solution which you would find satisfactory by criteria you are unwilling to provide?

Whether regulation should stop YT from doing this is a legitimate question. Nothing else will prevent it. Observe that the government telling a private company what they must host on their platform is potentially more dangerous than the government telling a private company to take down a piece of content (neither of these are happening here but if we entertain the notion of regulating YT then these are to be considered).

So as a denizen of the US I won’t be able to access Canadian YouTube?

That's for Canadian YouTube to decide in accordance with Canadian laws.

So you are advocating for every country to do what China is doing with their great firewall, or at least to have the ability to do so?
