Ultralight is free for non-commercial use and free for commercial use by companies with less than $100K gross annual revenue. Something that I have always asked myself is: If the code is open source, how would it ever be possible to enforce such a licensing model?

It isn't open-source in the "FOSS" sense. You can't have such terms in a FOSS license. However, you can have parts of a codebase be FOSS licensed, if the license is compatible with non-FOSS code. BSD, MIT and Apache licenses allow this, copyleft licenses like the GPL don't.

  GPL (and others) allow such a model as well. There is nothing in the GPL preventing me from selling for as much as I like. The buyer however has to receive the source code (upon request) and can share it for free (as in beer) if they like.

    I'm taking about using a license that has provisions such as "can only be used for free by entities with less than $100,000 in revenue" (this case) or "must not be used for evil" (jslint). Such a license would not be considered a free software license, because it restricts the use: https://opensource.org/osd.html https://opensource.org/osd.html As a result, the license would be incompatible with copyleft licenses. Of course, you could kindly ask your "customers" to please pay for a license in case they're using the software for some purpose. Good Luck with that.

That definition is really ambiguous for government use, I wish people would address that specifically in these clauses.

I had a brief look at the github repositories and don't think that all source code is available. At least I'm missing the source code of the core renderer. Maybe I didn't look close enough yet though.

  Ok, the website https://ultralig.ht/ https://ultralig.ht/ says "No source code for proprietary modules." for the free version. So it's technically not an open source project. I won't add closed-source binaries to my open source projects, so unfortunately this technology is not interesting, regardless whether it's good or not.
