The site linked to by the title is about mostly FLOSS projects for people doing audio/music creation work on Linux. The problems you're describing, in particular the licensing ones, are endemic to proprietary software. While this still affects e.g. Bitwig on Linux, it isn't really a feature of Linux audio software in general.

Cloud work so far just hasn't had much appeal. People are walking around with Apple M{1..5} laptops with enough compute power to do things you couldn't do on a studio system 10 years ago. Sure, if you're doing sample based playback with really high end sample libraries, or physically modelled synthesis, you can always max out any system with a large orchestral piece, but the stuff you can do on a laptop on a bus or train or the back of car really does encompass most of what most people want to be able to do.

iTunes was useless for people on Linux, just as any system that convinced Waves to participate in some sort of "implicit licensing" scheme would be (even though they run linux inside the hardware units they sell). Again, this link was to a set specifically concerned with the situation for audio work on Linux; until plugin developers en masse recognize it as a valid latform that they should support (improvements every day, but very slowly), this will as useless for Linux as iTunes was (and remains).
