I think different than you. If Satoshi Nakamoto is a group of people, they don't have to do anything. Silence means any finding, any hypothesis can be wrong. If they reappear to say anything, people can know Satoshi Nakamoto are still here with us, did not die yet. Sometimes, if you try to prove something is not about you, people will have more reason to think that it is you.
I merely believe that it will be some sort of protection mechanism if one of the Satoshis were to be exposed, especially if he/she was detained by the authorities. A signed PGP message would be enough to prove that they might have the wrong person.
That's a discussion for another topic. The other possible Satoshis that passed away were Hal Finney and Lens Sassaman. Lens Sassaman commited suicide.
I knew about Hal Finney, and knew he died with his chronic disease.
Bitcoin and me (Hal Finney)
I did not know about Lens Sassaman and honestly, I did not see anyone discuss about him in bitcointalk since 2017 before HBO movie.
Read his biography and check the date of his death. I won't say more, but something was announced by someone before he did it one month before the incident.
