Nothing dense in this, I don't quite know what to write either. In my opinion what you wrote in your comment is just perfect, you're a citizen simply expressing an honest concern, without lying – not all people are tech-savvy. It also makes it clear that it's a letter from a real person.

But that's only my point of view, and maybe I haven't thought enough steps ahead. Let's see what other people suggest and why.

Another dense citizen here. I ould say that you put it quite eloquently in your comment.

But direct the question towards them.

"Would googles new changes on their ad and user policy be affected by FTC data protection laws and GDPR or would they be in compliance"

Or something among those lines.
