What matters to me is that, when the GPL says you can't impose further
restrictions, then you can't, no matter how convoluted your argument
is

There was never any attempt to hide that this was what the Free
Software movement was about, and that the GPL was about defending
these freedoms.

Sure, it has other advantages. But the goal has always been the same,
and it's not going to change.

No, you interpret based on what the author wrote then.

You read the preamble, and any other rationales associated with the
license or law. I don't know how it's elsewhere, but in Brazil every
law has a rationale, and that's often used to guide its interpretation
in courts, even though the rationale is not part of the law.

If the author realizes what he wrote was not enough, or it got
misinterpreted, author his text, and then whoever feels like it and is
entitled to adopts the revised version.

In the GPLv2=>v3 case, all that needed revision was the legalese. The
preamble has barely changed. This is a strong indication that the
spirit remains the same, is it not?

Is there anything not clear about freedom #0, in the free software
definition, alluded to by the preamble that talks about free software
in very similar terms?
