Bitwarden is now verified on Flathub for Linux

The last I heard about that it turned out that the inclusion of a non free dependency was a packaging mistake and has been supposedly fixed

"The sdk-secrets repository and packages will no longer be referenced from the client apps, since that code is not used there."

Why? Is there a self-hosted version of proton pass available?

That's misleading. Their SDK which is used to build their enterprise product is no longer open source. You can still compile the main version without it.

There was a period where you couldn't, but it was a bug that has now been fixed.

If you would read the post you just linked, you could found the update at the bottom: https://www.phoronix.com/news/Bitwarden-Code-Cleared-Up

Stop spreading FUD, the issue was resolved, they separated correctly the foss and not foss parts of the software.

Not foss part only used on the server side on the cloud version, if you use the self hosted vaultwarden and any official client, everything is still foss, you can build it fron source.

Ok but it's an extra option for people who would like to use it. Why get angry at that?

Why? Flatpak doesn’t seem bad in my experience, except for downloading extra dependencies per program.

I actually understand your frustration and I don't know why you're being downvoted. I can never use flatpaks. They're actually very bad. They're definitely better than snaps, but they're terrible.
