Sure you can use lots of other password managers, but if we are not talking about solo use case - it's practically impossible to beat 1Pass. You can set up your team and family in minutes, with granular controls. And people will understand how to use it in a few minutes.
With most other solutions you will have to spend hours here or there. Is that time worth a few bucks? For me I would gladly pay x2 so it just works and no one has to bother me with questions.
I can't imagine paying for an application when a better one is available for free.
I see this as quite reasonable thinking for somebody who never had too much money.
Of course it might be that in this case the much more obvious is the case: throwing your most important data into a cloud on a close source system is kinda..."optimistic".
What happened, if not too sensitive to share, of course.
