I like to believe LARP security also boils down to having security that only exists to be shown off rather than having any major benefit. Kind of like Proton's entire "THE SECURE EMAIL™ BASED IN SWITZERLAND™" marketing shtick, and with PGP users showing off their keys everywhere.

As a customer, they're better as an alternative or ethical service - It's the closest bridge to mainstream email service that isn't completely piled on Google or Microsoft.
