@nielsk Ok, sorry, ignorance might be a bit strong. But again, you write "it happened and they don't know".
I think you weaken your argument and very important intention (as I understood it in the first place: "how can it be that 1PW doesn't have any issues?"), when you leave out the possibility that 1PW might be successful in not making these severe mistakes.
It's not that I'm convinced that 1PW has the holy grail of security management and does everything alright and will never have any problems. But they have a long history (longer than lastpass), that without incidents and a huge userbase in the Apple ecosystem. Which has or at least has had a lot of developers and security related folks actively working there.
