As mentioned in my post, there are tons of tools and derivative applications that can simply drop in any username/profile and access a full index of publicly available data about that profile/account: frequently used app and usage times, who blocked you, who did you block, your old username, etc… because PDS data is public. That is truly dangerous and concerning.

You may know or may not know, Brian Acton - the co-founder of WhatsApp, sold WhatsApp to Meta, and then co-founded the Signal Foundation.

Yes, it’s similar to Signal and a bunch of stuff out there. The founders of the tech industry are just moving the model from one name to another, disguising it as more progressive and secure, but essentially it’s still the same prison, and we’re just digital prisoners being moved from one prison to another.
