Why? I mean, by all means they've always felt like a true bootstrapping success story (I'm a happy 1Password customer for many years). Why take funding and give up control of your company to an outsider now?
You're not wrong. If the friction is low, user harm is minimal because they can move easily (the import from 1Password to Bitwarden was painless), and you're just burning someone else's VC dollars, I ain't even mad. No extra credit for making life harder than it has to be.
It sounds like they could have already done that given the success of the company? A company that's been profitable for 14 years has likely made its owners rich.
Is it really a matter of getting $4X M instead of $X M?
