And it's precisely this use (many would say "abuse") of copyleft to give
special privileges to one particular party which is opposed by many in
the free software world. The fact that it's a hassle to do does not mean
the OSI needs to make it easier.

Mozilla has a policy of not signing CLAs with commercial entities where
the software concerned is under a copyleft license, because we don't
believe it's right to give away special privileges to one entity like
this. If this license were approved, we would have to change our general
"OK to use" licensing policy from "anything OSI-approved" to "anything
OSI-approved apart from the Upstream Compatibility License".
