It would be better if we say that GPL and LGPL is unacceptable rather
than incompatible. Both the Apache 2 and the MIT licenses are defined to
be compatible with the GPL in the sense that they allow relicensing so
that the combined software can be released as GPL. But the board's
position is that Squeak shall always be under the Apache/MIT licenses,
so such a GPL image would not be Squeak but a new fork - that code can't
be accepted into the Trunk nor even into some future "full Squeak"
image.

To give you a concrete example, Self was released by Sun under an MIT
license. Some guys ported it to the x86 and Linux and decided to combine
it with gas (gnu assembler), so their version of Self was under the GPL.
In this case they were big fans of the GPL, but they really had no
choice (except for the choice of creating their own assembler). A few
years later, when the Mac moved to x86, Sun released their port under
the MIT license but didn't make any use of the previous work. So you
have to balance the need to keep people from "stealing" your work with
the possibility of them throwing away your work and doing it themselves.
