> But, the issue that people are starting to react to is - are some platforms a natural monopoly?
No.
> Is it useful to have all user-generated public video clips be aggregated by one central provider? The answer seems like it’s yes.
The answer is no.
Vimeo exists. Facebook and Twitter both feature user-generated video content. I hear TikTok is a thing. In addition to these platforms basically anyone can self-host in 2022. Plenty of news outlets self-host.
> If there’s only gonna be one platform, or it’s socially optimal to have one platform - is it right to give control of that to one entity into perpetuity?
You have not made the case that there should be only one platform so the second part of your statement is irrelevant.
> That a political question.
Only for people who want to say things without suffering the consequences.
