Permissiveness, or lack of it, isn't relevant at all. How I interpret the complaints with the 'no evil', the issue is the 'gotcha' factor, which arguably is out in full force with the AGPLv3. How many companies have botched handling even the GPLv2? We hear about it all the time.

I sincerely like the GPL and AGPL. I don't think potential confusion is a compelling argument against either, nor do I think it against the "do no evil" clause.
