Side note on communication here.
Any time someone uses a phrase like "Please educate yourself on $THING", they lose a lot of credibility, at least in the context of that communication. Why?
1) It comes across as incredibly dismissive of both any knowledge that that individual may have - especially on HN, I'm pretty sure we're all familiar with YouTube's scale - and of the idea that there may be missing information, on either the situation or context for the other persons point of view.
2) It's quite condescending as well - and if someone thinks that you are coming at a conversation from a combative place, they won't want to listen to what you are saying. Why should they listen if they think you don't care?
3) It's often used to paint broad strokes in places broad strokes may not be appropriate, and the phrase being attached to that makes it lose credibility even when it is appropriate.

Ok, now a response to the actual content:
I don't know why we've decided to allow things to exist "at scale" willy nilly. If something becomes a net negative "at scale", don't allow it to be "at scale".
No one is entitled to a business model.
