Security expert here.... This issa nothing Burger and will be fixed on the server side soon I expect. This is about spreading fear uncertainty and doubt. The research is academic in nature and the results are interesting, but this is only a side channel to reveal things like maybe you rough timezone and maybe a few correlations via connectivity quality. This is what they do if they need to confirm if a person uses the same phone number for example. And the could just look it up in the registry or maybe just call you...
This is not a widespread privacy concern, is not very practical to use, especially at scale and is early fixable. Its comparable to the traffic pattern analysis they do to confirm tor users identity if they found them but need supporting evidence. Its what's left when the technology works as intended. So chill your paranoia.
IT hobbyist here. This guy knows his stuff. Dangerous attacks are the ones that are very low effort with medium to high reward. This attack is high effort and low reward. This is one of these trivia things, that you will virtually never see in the wild.
High effort is not a great thing to count on. Once these things are discovered there are all sorts of clever (or not so clever) ways to automate the effort away. Especially now with AI.
