I don't understand how that works. So I have an Arduino library that has various Copyright messages including from Arduino and me. The licenses are a mix of MIT, GPL and ad-hoc license messages. How is Arduino able to change rights by updating terms of service? As to my understanding they don't even have the exclusive rights to begin with?

What does that mean for activities, that are already ongoing? And how can it be "reverse-engineering", when the board layouts are public and "decompiling", when the code is open-source?

How is the "Platform" defined? Every repository, that has Arduino in the name? Does Arduino assert ownership about random peoples Github Accounts? Because that is where the official libraries are hosted.
