> Lasso is a free software C library [...]
I wish people would stop saying "free software".
It was confusing from the beginning, and hasn't stopped being confusing.
Imagine RMS saying, "I'm glad you asked that. By 'free', we don't mean free as in beer (nor what everyone means when they search for some kind of 'free software'); we mean free as in freedom. Which I will proceed to speak about for half an hour, now that you're engaged by this small bit of wordplay that you had no reason to suspect was wordplay."
(Not that the ambiguity of "free software" was the cause of the Orange violation of Lasso. But, really, please stop calling it "free". Say "GPL", or some other license, or "libre", or anything other than "free".)
