I got the same email, and I agree with what you said - I'd really like to know if this is even personally relevant, and if it is, I'd really like to know precisely what information is relevant. I'm in the EU, so I guess I could ask under the GDPR, but I wouldn't even know who to ask, and with such a large organisation, I can only imagine there would be a lot of run-arpund, requiring a lot of follow-ups from me :/
