I don't actually know. At some point, we need to figure out how to address that question. I think it can be addressed... I just don't have a good idea, and I don't know that anyone does. But we've been kicking that can down the road for ages.
Work out the audience share of a service, then work out the audience share of its nearest competitor/competitors. If the former is twice/four times/whatever as high as the latter, then it's counted as a de facto monopoly and regulated.
So YouTube's got 74.08% of the market and Vimeo has 18.02%[1], and the former is definitely twice or four times more than the latter, so regulate the former.

We set a number. Done.
These are corporations that only exist because we permit them to. Given enough political will, we can regulate them however we want.
We're now back to square one, because those companies hover below said number and advertisers control what content is allowed on said sites. All of those individual companies ban 5G conspiracy theories because it's bad for business. Next step?
How do you really quantify that in a way that is objective and obvious
Look at the rise of tiktok. On one hand at least where I live they had almost no mindshare but in the past 2 months now they do, and they’re growing in user count. Should they meet the same threshold as YouTube now? Instagram?
This feels intractable to me, I don’t have a good answer to this problem. Not to mention it could easily become a gating mechanism to competition
Also, how do you determine what information is harmful? Some of it feels obvious, but some of it not so much
