Wrong, Keith.  This isn't the sort of claim you want to make while
attempting to become a respected writer on software topics, although
you are in good company with many technical journalists.

With the exception of pure-BSD purists (who reject the patent clauses)
AL can be mixed with any code to come out with the more restrictive of
the licenses.

AL + BSD == AL
AL + MPL == MPL
AL + GPL == GPL

The following are not possible;

AL + BSD != BSD
AL + MPL != MPL
AL + GPL != AL

So the input AL code can be combined as a donor to any effort and result
in an appropriate license to the finished effort.

The converse cannot be said of GPL, which explicitly prohibits additional
terms or conditions on the resulting license.  GPL is type AB+, as it can
not produce other outcome.

Perhaps your ignorance comes from medical science, though?  You supposedly
learned this in 6th grade, but I wouldn't brag about your report card.
