It is official that the FSF accepts them. This does not mean that a court will. If I place my program under the GPL, I am the one who would sue you. A court would not particularly care what the FSF thinks the GPL means, they would care what the GPL actually says and what I mean when I placed my program under it.

The plain language of the GPL does not permit a requirement that you maintain a list of licensing terms other than the GPL. This license requires you to do just that.

I agree with everything but the last part. The GPL does not permit you to require anyone to maintain any licensing language other than the GPL itself but his license does. That makes them incompatible.

The problem is the "this list of conditions". Please show me where the GPL permits you to have a list of restrictions (other than the GPL itself) that people are prohibited from removing when they distribute the work.

Again, please show me the GPL section that permits this restriction. I see no GPL section that permits you to prevent people from removing a "list of conditions" when they distribute a work.

I'm right. The FSF, and you, are wrong. If you are correct, quote the GPL section that permits you to prohibit people from removing a list of conditions for copying/distributing.
