I dunno, but it doesn't really seem like Privacy or Competition is the right angle for this, they're luxuries after all, and it's not really relevant for those political maneuverings. Security is more important. The right actors could hack the entire financial system and more with these kinds of vulnerabilities, with targeted sim swaps. Take for example, the currently unfolding Twitter hack that puts 400m Twitter users' phone numbers up for grabs - including every big fish there is.

Call yourself an anonymous Russian hacker and that might get their attention.
