Author of ATSC Capture and Edit Tool Tries to Revoke GPL

The author of ATSC capture and edit tool has announced that he is attempting to revoke the licensing of his product under the GPL General Public License. Unfortunately it appears that the GPL does not allow this particular action. Of course in this heyday of lawyers and trigger happy litigators who can tell. What successes have others had in trying to take something they once operated under the GPL and make it private? And the more pressing question, why?

Actually, there's a good question in there.

The GPL states that if you are restricted from distributing a work due to other encumbrances, you must refrain from distributing under GPL as well. It's not intended to be a rights-laundering license.

So the question is (or rather my question, since I'm sure actual legal scholars have already debated it to death) if it turns out that someone up the chain did not have the right to distribute under GPL, does that propagate down the chain to all those who unknowingly redistributed software for which the authority to actually do so was never transferred to them by someone who had it?

No. The copyright holder is not bound by the GPL.
The copyright holder is bound by copyright law.
Other people who have copies are bound by the GPL (and copyright law).

The issue at hand here is really if: he can give people permission to redistribute using the code, and then change his mind after they've already received it under that agreement. If I had a copy, then he has already given me permission to redistribute without checking with him. He's now saying that only he can give permission to redistribute. What if I never check with him? He didn't require me to before. How am I expected to know? Am I bound by his new decession, or may I argue that I have received permission and am relying on it?

The "three years" clause that you mentioned only applies to someone distributing a binary without the source.

There is nothing in the GPL that says that he is obligated to do anything once he has released the code. He may cease to distribute entirely; he may distribute under a different licence of his choosing. The only question is: does copyright law allow him to revoke such a permission once granted?

IANAL
