For my own purposes, open weights are 95% as good, to be honest. I understand that not everyone will agree with that. As long as training takes hundreds of millions of dollars' worth of somebody else's compute, we're always going to be at the big companies' mercy to some extent.

At some point they will start to restrict access, as you suggest, and that's the point where the righteous indignation displayed by the neo-Luddites will be necessary and helpful. What I advocate is simply to save up enough outrage for that battle. Don't waste your passion defending legacy copyright interests.
