Everything described in the thread has been going on since the Patriot Act was signed in 2001.
As early as 2010, I was able to look up ANY IMEI/IMSI combo in Proton and see all links to other IMEI/SI collected worldwide.
By 2013 I could query those in Palantir on a Secret or SCI level depending on who held the data which would also aggregate and provide to me OSINT, LE reports or other data associated with those id
What’s new here?
Is it just that more people know about it now?
All the stuff I described above was public information as to both “capabilities” and used as casus belli for warrants (US) or kinetic actions (OCONUS).
