Do you have data on that last bit, or just a guess? As a hobbyist and OSS developer I treat AGPL as a rabies infected animal. I may have uses for it, but I'll keep it EXTREMELY segregated from everything else.

Which fine, you can choose to take that political stance. But that's a stance of "I want to change the world to my liking", not "I want to help the world/people".
Up to you, of course, but I prefer to help not only large companies.
And hell, even without money involved, I'm not going to make a hobby project with AGPL software either. Not only may I have small parts of the project I've not opensourced, but AGPL is untested in how far the virality goes. Are my backup cronjobs in scope? I certainly don't want to be the test case for this. Even if I win against an AGPL troll, I'll still lose.
