a) Is there an example of a cloud provider adopting or building on top of your existing AGPL code bases? The big 3 all have fairly well known internal policies that forbid AGPL use. Ever wonder why there isn't there a MongoDB service being offered by any of the major cloud providers? AGPL.
All that being said I doubt they would want your modules anyways. Their track record tends to be:
* AWS would grab the core BSD licensed project, ignore your management tooling regardless of license, and build their own management tooling that integrates with their ecosystem. Theres a few exceptions to this like [Chef and AWS on OpsWorks](https://twitter.com/adamhjk/status/1032312528196575234).
* Google. They wont use your software either. If anything they'll build some wizbang redis like protocol and interface on one of their internal proprietary databases. All the software will work the same, but it'll be "better" because its powered by BigTable/Spanner/whatever.
* Microsoft. 50/50 shot they might actually just license your code and partner if they thought customers wanted it.
b) I'm not surprised that large customers aren't AGPL fans. Isn't this where they should come in with a dual-license approach and sell commercial licenses to the software you develop? So whats the win here?
