The Green Party is a mouthpiece for Russia. Look at this recent press release: https://www.cornelwest24.org/war_climate_and_my_presidential_campaign
I was going to try to explain how insane this release is, but honestly just read it for yourself.
As far as privacy and tracking go, can you unpack that a little more? Isn’t everything you post on the fediverse totally public to begin with- isn’t even already likely that they have spun up servers to test ActivityPub integration with, that have already pulled your fediverse posts? This just seems like a symbolic gesture more than anything.
Checked out this guy’s profile, once again the fake enlightened centrist is really just a right winger.
