This is absurd. Seriously, read the EULA: https://github.com/wixtoolset/wix/blob/main/OSMFEULA.txt

This fee only governs the binaries compiled directly by the company. You can "circumvent" this license by building the software yourself, or having someone else build the software.

Right now I can click the download button on their github build, what then? They do not even link to to the EULA there, yet the EULA stipulates that this exchange requires me to pay money to them. The github statement stipulates that paying money requires me to first pay the maintenance fee, which is not part of the EULA, why? What is the point.

Here is a tip: If you want to make money, make it easy to give you money. Right now any legitimate company has to fear walking into legal troubles with this. Can you imagine how the discussion with accounting is going to go?

So far the only hard conversations with accounting are how to pay by invoice (since GitHub Sponsors invoice handling is a bit wonky). Those that pay by credit card have pretty universally been, "Oh, this is easy. Done."

Correct. By design. The software is Open Source. That's the whole point.
