One of the really fascinating aspects of this whole thing, at least to

someone with a classic liberal arts education, is how poorly technical

people often perform when faced with natural language text.  Not all

of them, obviously, but it's amazing how often it happens, even with

people whose high intelligence is indisputable.  You see the full

panoply of logical fallacy at work.  They try to do things they would

never try with technical specs.
For example, "you may choose a license for distribution".  There seems

to be an overpowering urge among some to read this as "you may may

choose a license for removal".  This is an obvious non sequitur.  The

reasoning seems to be something like
   premise a:  you may choose BSD or GPL

   premise b:  you may distribute under your chosen license

   conclusion: therefore you may distribute without the other license
Fallacy of Equivocation:  use of a term with two or more meanings, as

in, using "distribute" to mean "alter", or taking "choose A" to mean

"remove B".

Fallacy of Illicit Process: a term in the conclusion has a wider

extension than in the predicate (i.e. going from "some lawyers are

cheats" to "all lawyers are X"); this non sequitur doesn't quite fit

the definition, but it does involve similar chicanery, going from

"choose A" to "choose A and remove B".
I'm sure this bit of faulty reasoning commits a few other fallacies as

well.  In any case, it's amazing how many technical people are willing

to take OR as a synonym for EXCLUSIVE OR.
The only way this will get clarity in the end is in the courts.  In

this case, the people pulling these shenanigans - possibly including

the FSF - richly deserve the RIAA treatment.  Maybe the foundation

should create a fund for defending the license.    (And I'm not even

religious about this stuff - it just really irks may that these people

pontificating  about freedom are willing to behave so selfishly and

disingenuously.  And illegally.)
