Apples and oranges. There's a big difference between starting an "educational institution" and sharing knowledge or otherwise teaching for pay as an individual.

And, in the case of the boot camps you mentioned, it kind of argues against your original point. That is, they apparently ran afoul of the regulations because of their attempts to make it a business that could be classified as an institution versus there being individuals who could have generated income from their labor, if not for some onerous regulation.

More relevantly, no one would have stopped any "teacher" from creating Udemy style online courses on their own domain.

That situation in CA is intresting though. I wasn't aware of that. Thanks for sharing.
