Adobe does not sell a software library and you don't need to distribute anything from them, just the output of their software. Of which, at least for now, they haven't managed to take ownership. However, for libs like, say, Qt and this library, it's different. I haven't looked closely at licenses for subscription based stuff, has anyone?
