They are both really bad for privacy. There's really no point in comparing them based on this criteria.
Given that we're on HN, I distinctly remember reading on a comment that the new Edge supposedly dials home to MS and is not really secure either.
At least, if you're on Windows you pretty much already have to trust Microsoft, so you may as well not have to trust Google AS WELL.
The concern is not that Chrome dials home to Google, but that any random dude scatters your data across entire internet.
My comment is the answer to a specific comment asking about a tangential derivative based on the discussion (which is why it is not a new parent comment under the post itself). Thank you.
Yeah, I mean a disconnected reply to a tangential question is misleading.
