No part of any open source license says I have to like companies that extract billions in value from open source projects without contributing back to the project. My opinion is simply that once you get to a few million in revenue putting a few thousand back in to the code that got you there is a decent thing to do, and if you don't then you're not very nice.

The fact that the license allows you to do this is great; the fact that people actually do is not.

GPL asks to release back changes to code made by a company, for which the company paid already, i.e. it's almost zero price for the company, and just look how much companies are afraid to donate zero ($0) worth of code back to the opensource project and prefer to pirate it instead, including such mega-rich companies as M$.

Only if the code is distributed. SaaS can be (and is) used to get around this.

Hence the AGPL.
