Regarding hobbyists: some clouds, and also the bigger clouds, do target hobbyists quite a lot, presumably with the intention that some of those hobbyists will eventually grow and stick with them. So I don't think "not wanting hobbyists" is entirely true.
But yes, the amount of money they spend is less, so it makes less sense to implement features that only hobbyists want.
