Archival options for deceased or otherwise historically significant accounts
There's an internet activist who's on the way to expose serious community and structural scandals in a well-known encyclopedia platform which could very well become another Epstein moment if they got their wish. In anticipation of that they said on X that they're gonna voluntarily donate their web accounts and so on for congressional investigations and subsequent archival preservation one day.

Whether it's crazy for you is an open question but inspired by that, I want to suggest that Protonmail offers options for those who want their accounts to be archived/locked forever upon death which can either be proven by documentation from those who the deceased had delegated the power of attorney, or by automatic assumption once the user had tweak a special setting in the account dashboard on where they will be automatically assumed as deceased upon five years of account inactivity.
In the case of that internet activist, I suggest Proton to reach them out as soon as possible so to discuss their arrangements further. Just for a perspective, they repeatedly said that in the age of deepfakes, lies are just as likely as to arise from the absence of data than the presence of it.
Even as email messages in Protonmail accounts are unreadable because of end-to-end encryption, their titles should still be useful for archaeological researches for digital humanities far in the future because they are one of the only few that are not subject to end-to-end encryption.
