Could we all please take a deep breath and not escalate things here?
As far as I can tell, Corbin is attempting to comply with the GPL and
is actually doing more than is required. Before accusing him of
intentionally breaking the license, let's assume that he will fix any
problems if he is made aware of them.
The GPL definitely allows binaries to be distributed only to customers
who pay. I don't see any significant difference between that and
allowing the binaries to work only if they have been paid for, though
whether this is allowed or not depends on the mechanism used to
prevent the binaries from working. In any case, I would just
recommend to Corbin that he simply limit distribution to those who
have paid, if that is what he wants to do. He is under no obligation
to distribute binaries free of charge.
In the context of this discussion, his obligations are:
* Provide *to the people who have paid for the binaries* the exact
sources and build system that he used for the binary version that
he is distributing. He is not required to provide sources to
everyone who asks.
* Allow anyone who receives a copy to redistribute it under the same
terms (the GPL). So it is perfectly acceptable for someone to
take Corbin's binaries and redistribute them, provided that they
also comply with the terms of the GPL. If the disabled binaries
can't be redistributed without the restriction on paying, then
that is possibly in conflict with the GPL.
Finally, Corbin has clearly done a lot of work on building Octave for
Android. I don't think there is anything wrong with him getting some
money for that effort. Similarly, the people who wrote Octave and
various packages have also done a lot of work and some would also like
to receive compensation. It would be great if Corbin shared something
with the other people who have made Octave on Android possible, but he
is under no legal obligation to do so.
FWIW, this kind of issue has come up for me in the past with the
Octave manual. One person who has sold it did contribute a (very
small) portion of each sale but others have not.
