Lots of foss use dual license: free for individual or non-profit use, but pay for commercial use, or even commercial use above a specific threshold. As part of my job, I’ve had to remove several of these, where the developer thinks it’s free but the corp can’t comply with the free licensing. It works.

Here’s an extremely well known example

• https://docs.docker.com/subscription/desktop-license/

I still haven’t decided what kind of company mine is with respect to foss. Its a good thing that they put effort into complying with licensing terms, they do support developers making contributions back, and historically they’ve “bought” a few foss projects (hire the developer, include that in his job responsibilities)! However I haven’t yet seen them make a corporate contribution and the first response with being out of compliance is to remove the dependency.

So it’s good that we take it seriously, and good that we historically contributed, however we don’t seem to co tribute much anymore and clearly get more benefit from foss than we give back
