It is a way to make some income out of an open-source project. If you want the convenience of their managed server, then you have to pay to access limitless orgs (the way to share secrets), otherwise you’re limited to just a 2-person org. The family pack is quite accessible imo, at $40/y for a 6-person org.
Your other solution is, like I mentioned before, host your own server. vaultwarden supports orgs, like you can see in their feature list: https://github.com/dani-garcia/vaultwarden/wiki

BitWarden is really great and a good example of a successful FLOSS project. I get the overall “companies just want to screw you up”, but one must not get completely blinded by it ;)

BitWarden,¹ it just works really really well everywhere. The app is pretty much the same on every platform (which is a good thing imo) and you also have a CLI in case you prefer (may also be useful in some sort of backup script, I suppose). I personally use the cloud service they provide, but you could very easily and cheaply get a vaultwarden² server up and running and be the total master of your passwords, using a $2.5/m VPS or something like that.

Edit: also, the premium Bitwarden plan doesn’t mean that at all, imo. The plan can be very useful if you really need those features (sidenote: I advise ever using the TOTP thing, that’s just putting all your eggs into one basket and defeating the purpose of 2FA), it’s very cheap ($10/y iirc) and you can always export all your data with the CLI, setup a server and import that data.

Vim and neovim have mouse support as well. Micro has less plugins and is overall less configurable than (neo)vim. The style sure is different, but in terms of features, vim outclasses micro atm.
