i like alternativeto.net because it's crowdsourced; not sure about the others

immutable distros (e.g. fedora atomic desktops) are secure in the sense that they're containerized. if that's something you're after, i don't see why it wouldn't be a good fit for you.

they do rely on flatpaks, so you'll need to make sure davinci resolve comes as one. it doesn't seem to be on flathub, but i do see someone else has packaged it. if that runs well, i think you'd have nothing to worry about.

why not pgp? there are browser extensions like mailvelope

this is the founder, so no.

PikaPods or YunoHost

fwiw, system76 support is actually pretty responsive, if you want to try them. they even have their own mattermost server for quicker responses.

it does. and with a community server (which can still be made invite-only), you can even make "forum" channels.

i also have the same grievances with surf.

but none seem to have any of the rest of the features, unfortunately.

there's also lemsha.re and voyager's go.getvoyager.app

Zulip, Mattermost, and rocket.chat all have threads. Discord would be the easiest.

i use mobile apps. i honestly picked purely based on ui design. i personally like Voyager and Thunder the most. i went with Voyager because it allows choosing a post layout per community while Thunder doesn't (as far as i can tell).

Fairphone?

i think it's the firefox new tab page

i've seen commercials of Gemini doing this. not sure how accurate it is realistically...

Nagram or Momogram, or Mercurygram which is a fork of Telegram-FOSS. none are on f-droid though, just github releases

!buyitforlife@slrpnk.net?

you may want to go with cardDAV. you can self-host radicale, sabre, & baïkal. some email providers even offer it

AppListBackup is the closest i've found to this, but it can't filter by install source

don't forget Discord victims users
