The AGPL is a great license for free software development. It is also great to be coupled with a proprietary license, something that does no often make sense with other licenses.
Its a fine revenue stream for me, and in the context of what I am building and the companies that are using it, there is absolutely no reason to not use the AGPLv3 licensed master branch or releases, as I know they will never extend my software. Yet some people have an axe to grind with AGPLv3, to which I get to respond "Pay me money or fuck off". Seeing as none of them understand how to write software, they tend to pay me :P
Worst case someone extends one of my AGPLv3 projects, adding features and improving it. I'll accept a pull request with no CLA so long as the code is of decent quality.
