Ariadne Conill of Alpine Linux published this article today, which I agree with wholeheartedly:

I'm a fan of the GNU GPL, especially version 3. I actually think version 3 is the best version, for several reasons. The events of 2021 have made me worry about GPLv4 and what that might bring, if it ever comes about, so I'm interested in removing the "or later" clauses, whenever permissible to do so, in my own projects.
