Here’s an example of what I want to do: ship our application entirely open source/free (AGPL3), but with options for interested parties who want to pay us for support/consulting to do so. Likewise, we want interested parties who want to build their own proprietary app on top of our stack to be able to do so.

Mixing in a “you have to pay if you’re a corporation” licence makes this difficult if not impossible, particularly if we wanted deep integration with eg Cactus. We don’t want to police a “corporation” who wants to use our open source software.

Thanks for pointing this out, another factor for us to figure out. We waive the license for such cases, wanna get in touch? I don’t think your consumers have to worry about the license.
