$10/yr is not a big price for what you get. I don't think I even use the extra features you get with the subscription, but supporting the maintenance and development of a product I would like to use for years to come is important.
Agreed. I like that the free version works well. The lack of pressure or nagging toward paying is what gets me to want to pay. I usually avoid subscriptions.
I usually self host but the fact that the option is there and I can use it any time in the future is the main reason i use BW and kick them a bit of money. And not bring nagged or forced to subscribe is a major factor for me as well.
I switched to bitwarden when last pass announced they were changing there free model so you can only use your passwords on browser or mobile but not both. Liked bitwarden way better and immediately did the yearly sub to support them.
