I really think the whole AGPL is simply sour grapes, because most GPL-using businesses have not figured out how to become profitable. ("open source is not a business model.") The anti-corporate, anti-business types see people exercising their software freedoms and using free software to make money, and think it's a problem that needs to be stopped.
It's interesting that TPTB have ruled such "ethical source" licenses as nonfree - you're not allowed to restrict Freedom 0 to say that users aren't allowed to, say, use the software to produce bombs. That's not a free software license.
Using it to generate revenue however, is seen as a "loophole" to be "closed".
I don't see a license that forbids the generation of revenue by selling access to a service API using a private fork as any less nonfree than one that forbids the production of bombs.
