Ghostery was involved in some weird info-selling controversy, weren’t they?

Edit: I looked it up. Yup, they were selling info about the trackers they blocked to the tracking companies they were blocking. So those companies could then figure out how Ghostery was blocking them, and circumvent it.

Apparently after that, they had another controversy where they started inserting ads to show to their users. Somehow that feels even worse, because the users who had it installed were trying to avoid things exactly like that.
