Would be interesting to know why there is no EU option. One possibility is they do not have enough data to offer it; that's good news for EU residents. Another is they want to avoid the costs of GCPR compliance and the possibility of regulatory action in the EU that is de minimis in the US. Either way, the fact they have no EU option does not inspire confidence they are on the users' side. The US is incredibly friendly to these shady "businesses". As such, US residents are "sitting ducks". Very sad. The way to stop this nonsense is with laws not more people accessing the data; trying to label "good guys" and "bad guys" does not work.
Incidentally the same "confirm your data" issue exists every time there is a data breach and people set up "Have I been pwned" websites allowing people to search for their name/e-mail address in the data. (Instead of allowing them download the data and providing instructions how to search it in private.) Not every one of those sites is legit. It is an easy way to at least confirm there is a live advertising target who is actively concerned about this data, and we have an originating IP address for that person. That seems to be what many tech companies want to know, "Is it really you?", so they can more convincingly market "you" as a real target for online advertising.
