But here the source is open!
Why should we restrict the meaning of Opel Source, a societal mouvement since decades, to a list of criteria that FSF or OSI decided?
Open source is not a trade mark by FSF or OSI.
OP did not say it is free/libre software, but just open source, which it is.
We don't need "source available", just open source is correct.
PS: can you define the open source body in your previous comment?
