@chsxf I could be wrong, but my understanding is that the license applies to copiers, the right holder can do whatever. Additionally, I think it's not that no commercialization can be done, it's just that you cannot without the explicit permission of the rights holder.
The idea behind the restriction would just be to prevent someone from selling their own version on mobile app stores or something, which... tends to happen even without freely available source anyway, but still.
@lyon Always buy, because I have no idea how to build it, and I don't have time or patience to learn.
I know Mastodon is a programmer-heavy space, but I feel like programmers always overestimate the capabilities of their users. You didn't even list an option for "I don't even know how to build a program from it's source code". Insert that XKCD about geologists thinking everyone knows about geology.
@lyon I voted "Purchase anyway, building is just enough friction", but to be more precise, it's not necessary that "building is just enough friction", but that I value the fact of paying for the work done and encouraging the initiative.
On a similar topic, I buy all my games on GOG to value and encourage DRM-free games and selling platforms (and also EU businesses).
