Interesting article but the issue is that it's mashing together the Chromium Browser and Google Chrome. I'm sure that Chromium itself is safe but the prvacy concers arise from the "Google bits" rather that the browser engine itself.
Some of the statements in this article are just not true. The post seems to get frequent edits and always looks new/recent when I visit it, though I’ve seen and rebutted it several times over the last years. Yet, apparently nobody made the effort to verify the claims with more recent analyses.
