In practice, projects that take this approach do the majority of development in house, and external contributions are small. It makes sense that a company that may have spent several years developing a product can sell commercial licensing. The only alternative way to monetize AGPL works is to provide services and support.

Nobody is forcing anyone to give away their rights. You can always distribute contributions under AGPL in a forked repo.

The alternative is that if you're making meaningful contributions then it's in the company's best interest to hire you full time to do it.

Contributing upstream can benefit the ecosystem around the project, and the money that comes from commercial licensing also benefits it. In some cases the project would die if it didn't have the commercial side. They're not running a charity and if they aren't generating enough revenue they'd likely be working on something else rather than maintaining a FOSS project that doesn't make any money.

I love single-license-per-project F/OSS companies like Red Hat, but they're rare. I'm attracted to companies who are so committed to F/OSS as a practice that their software is copyleft and they don't require a CLA.

But dual-licensing is a tried-and-true strategy and the basic premise is very clear and very fair: share your downstream changes or pay a fee. And a CLA is required to make that work.

Something commenters here seem to miss is that all permissively licensed software is vulnerable to the same kind of maneuver that copyleft+CLA software is. If MIT or Apache don't scare you, neither should GPL+CLA.

There are clear differences. [Let's say I am not a competitor and Amazonifying them] I can keep using a permissively licensed software or a fork of it at the moment they pull the rug and keep using it in the same manner; I just don't get future updates. I cannot fork AGPL and use it commercially in any reasonable manner.

Even worse, let's say I am a paid customer for their support and run on their proprietary license. Once they rug pull or jack up the prices or whatever, I cannot fall back to AGPL hosted locally. If it were permissive I would have had other options.

AGPL I fully respect as Free Software. AGPL+CLA, however, is not your friend and is pure deception. If you are a sufficiently large commercial entity, you are probably wise to act as if it is proprietary. In fact, it might be slightly worse as folks are sometimes cavalier in accepting contributions without proper copyright license/assignment and they pass them on to you under their paid license and expose you to some risk.
