Reading the text of GPLv3 closely, I was disappointed at how little its additional provisions actually protect. It read like it guarded against Tivoisation and not much else, but the world's moved on since then.

GPLv3 either went too far, or not far enough (in terms of cost incurred: gaining enough ground that the community split is worthwhile, volume of license text, ...).

If I had a time machine, I'd suggest the FSF to try frog-boiling people into software freedom instead.
