< Clearing conversations, why is it offensive?
I get that. The question is - why does it bother people to not have an archive of our conversations? That's kinda creepy imho.
As a datahoarder, I think it's neat having an archive of my entire life (provided I have complete control over this archive and it's not in the hands of any FAANG or something).
As a social thing, I don't see it as creepy, I see it as wanting to preserve the history of a relationship. It's the same reason why we save written letters from loved ones.
I still have chat logs from when my wife and I courted between 2000 and 2004, along with our emails. You might think it's creepy, but those archives are part of our history. We can read through them together and remember when we were young and in love despite being on opposite sides of the planet.
