I remember reading about this when it was first proposed shortly after 9/11 and thinking "who in their right mind would want a cell phone now?"

Pretty sure Amdocs is still commissioned to monitor & log all telecommunications, which is why I encourage all text/phone calls over #signal if possible

Wiki:

•1982, founded in Israel as offshoot of Israeli phone directory company Golden Pages: Owned by Aurec Group, headed by Morris Kahn.

•1985, Southwestern Bell acquires 50% ownership share of Aurec, name changed to Amdocs. In two years, Aurec Group sold all Amdocs holdings for ~$1 billion
