A non-trivial number of contributions to Wine come from CodeWeavers (30%+ of all commits), which in turn is funded by its work on Crossover, Proton, and commercial agreements with other businesses. Wine would not be the project it is today without the contributions of CodeWeavers. Contributing cash to the companies contributing code is a perfectly adequete form of giving back.
CodeWeavers released an annoucement when Gaming Portal Toolkit was announced.
The announcement says practically nothing except “we did not work with Apple on this project.” And then a bunch of comments about the license Apple gave their version of the source code.
You sure there was any kind of commercial agreement? Doesn’t look like it.
