If they use AGPL, how would they get companies to actually use the software before extorti^w shaming them into paying some money for a product they are licensed to use for free?

Developers: think long and hard about the license that's right for your project before you push out to the world. I can't help but feel that free/open source software has become a lot less altruistic in the era of Github. We gained quantity and quality, but lost something else that's difficult to express: innocence? Not every project needs to be a job/startup/foundation (cue Left-Pad LLC). I daresay, not all projects ought to be monetized, period.
