They switched from a purchase with local vault storage model (where you could sync it to the cloud if you wanted to) to subscription-only with cloud storage they control.
They sent an email a couple months ago stating prices were increasing as of Mar 27. The family plan went from $59.88 USD per year to $71.88 But it's still worth it IMO.
That is a pretty big price bump though, and I think it's going to cost them. It's certainly enough that I'll reconsider Bitwarden.
