I feel like a version of this guide gets reposted weekly, but it’s always out of date.
u/theFallenWalnut over on that other site updates these regularly.
They also now link to !purchasewithpurpose@lemmy.world but I don’t see anything posted there. Maybe a better place to start reposting these
I personally wouldn’t recommend proton mail https://theintercept.com/2025/01/28/proton-mail-andy-yen-trump-republicans/
