Chief Executive Officer @ Guardian (https://guardianapp.com).
previously: founder of "Chronic Dev Team" & worked on many years of iOS jailbreaking solutions (24kPwn, absinthe, corona, greenpois0n, etc).
I believe this is correct, in fact (someone please correct me if I've got this wrong?) it looks as if this open source tool being cited is incorrectly labelling TMSIs as IMSIs.
That sounds nice though.
Additionally, an OIG report seems to suggest they did not attempt their usual avenue for acquiring access tools in order to get in, instead trying to force a legal precedent.
The initial default will be to simply offer a button called “Protect” and app handles all the rest.
That said, in the future, lists will be published for folks with the ability and time to operate a Pi-Hole for themselves, if preferred.
The only app I have found this happen with is Uber:

It is a genuinely tricky challenge from their perspective.
This is a good thing for any apps who do things right.
Also, we will either provide a searchable app index, or freely share findings/info with parties such as Exodus (This has not been fully decided as of yet).
This is indeed what we (originators of this location tracking research) do.
Please feel free to send a message at any time, even if you would just like to compare notes on all this (hello@sudosecuritygroup.com).
The good news is that only that last part is required if you would like to try this, now that the commonly used hostnames are published.
Folks can add the full list to a system such as Pi-Hole, and if they notice any hits for the listed servers, they can then route their device traffic through a tool such as Bettercap or Burp Suite in order to discover the offending app(s) and what information they are sending.
