This is a fair comment. I'm not saying that there couldn't be better privacy practices in place (while I think Google is better than average here, we aren' perfect and to your point I think a lot of people within Google recognize that). But the question here is what part of this is sneaky? Is including a weird tracking header sneaky? Perhaps. Is making requests to doubleclick sneaky? In the context of those requests being made as part of a page load? Not on the part of Google, which is my point. The original complaint was that the header was being sent > That Google need to send "experimental headers" to a hardcoded domain for an advertising company they bought a decade or so back - because of course the results of web browser experiments should go to an advertising company And the reason why is simple: that's the domain people are already making requests to.
