They do the same shit with the GPLv3 as well. Piko Interactive recently backed out of a licensing agreement with me, and just released my GPLv3 emulator in their Steam application without even telling me. When someone called them on it, they said to e-mail them for a link to the code (not enough to take my work for free, they have to play games with their obligations under the GPL.) Which by itself is useless, as it's just a UI modification. The value is the ROM image they don't include in their source, which gets you into a nasty gray area of the GPL.

It's part of the Faustian bargain all open source devs have to make: if you add a non-commercial clause, FOSS proponents will label your work "non-free" and "not open source", and you'll be banished to obscure disabled-by-default nonfree repositories on Linux distros. Which I was until I caved and moved to GPL to avoid punishing my users.

If you don't add that clause, you'll get taken advantage of. We have to rely on people being fair and sharing their profits off our work, and very often, they don't.
