Seems so, but keep in mind that it can provide that UX without being able to recover the individual data about who downloaded what.

Sure, but I don't remember being asked to share this information either, that's the issue here.

Actually, they can provide that (somewhat publicly responsible) UX by extension without tracking at all. It doesn't sound very "googly" to do so, but who knows, maybe they do... ;)

I don't understand what you mean here. How can aggregate long download stats exist without aggregation?

if (extension === zip || tar || ...) then "This file is not commonly downloaded and may be dangerous."

Kind of like putting a warning sign at the swamp without poking for alligators (or yodas)

> Chrome Warning: This file is not commonly downloaded and may be dangerous.

The warning is about download frequency of a particular file, not filetype.

This. I've gotten it when redownloading old PS2 homebrew stuff that I'd used in the past and knew was safe, and that's about it. They were mostly zip and exe files.
