The agreement does put a lot of limits on what the FSF can do with it. https://www.dreamsongs.com/IHE/IHE-110.html https://www.dreamsongs.com/IHE/IHE-110.html >The Foundation promises that all distribution of the Work, or of any work "based on the Work," that takes place under the control of the Foundation or its assignees, shall be on terms that explicitly and perpetually permit anyone possessing a copy of the work to which the terms apply, and possessing accurate notice of these terms, to redistribute copies of the work to anyone on the same terms. It goes on like that for a bit, to essentially promise that your software will always stay free (as in freedom). It also gives you (but not the FSF) the right to use your own code in proprietary software, with 30 days notice. It's unlike CLAs as described in the article.
