It wouldn't be a problem if there was a clear statement from Mozilla, or from Yandex. However, both declined to comment (as of now) because, obviously, the talk might give the users the revelation they have been sold and resold like cattle.

I've been installing Firefox with useful extensions on all computers of friends and relatives (if only because it's not fucking Google Chrome Cage), and now they got a shovelful of shit straight from Mozilla.
