Looks like the https://www.eff.org EFF’s spearheading it. I’ve been a fan of theirs for their existence – I remember when they were founded, saw the initial drafting papers on the younger internet – 1990 on Usenet. I was only 18 but it made an impression that they were looking decades ahead of anybody.
I can’t say I agree with everything they fight for. I think some of their fights have been silly.
