Makes sense. I also read they are working on allowing it to work for other wallets than Bitkeys, so indeed, might not be an evil ploy. But for now, it's what keeps me from activating the inheritance feature.

I'd guess that's more like a happy coincidence than intentional. The beneficiary needs to hold key material for this to work and the ability to execute this protocol. This seems like both the easiest way to do that and it has these positive side effects.

Bitkey’s inheritance feature: A technical deep dive

So they beneficiary needs their own Bitkey. That's a smart way to onboard more people and/or sell more devices. Even to people who might not use it for years until their benefactors die.
