Update: Bitwarden posted to X this evening to reaffirm that it's a "packaging bug" and that "Bitwarden remains committed to the open source licensing model."
I'm not going to jump ship just yet, though I may get around to updating my backup.
There are plenty of alternatives, so feel free to shop around. But don't jump the gun just because of a random Phoronix article with an update that says basically the opposite of what the article claims. Wait some time to see if there are actual changes coming.
