Sure; "good" is a rather wider domain than "open source" :-).  My point
is just don't call it "open source" if it isn't -- people are counting
on those words meaning something specific & dependable.  They'll think
they can fork the code, or, you know, base a business on it, and then be
surprised when the license bites them.
