Apple Public Source License - is it OSI certified?

[Ken Arromdee]

Personally I object to the APSL because of Apple's right to withdraw it
if there is a claim of infringement.  The problem is that this means that
the janitor's mother-in-law could say "I think the whole thing infringes"
and the entire source code would be withdrawn; the license doesn't require
that the claim be one which is made in court.  (And the clause requiring
Apple to un-withdraw the rights if they win in court doesn't apply if it never
_goes_ to court.)

But I'm a layman with no legal training whatsoever.
