Hell finally freezes over ...

As of October 2020, apparently Microsoft will be releasing a native Linux version of their Edge browser.

Hands up everyone running Linux who wants to install Microsoft software on their machine?
(Edge seems to be based on Google’s Chromium browser engine, although Wikipedia lists the browser itself as having a Proprietary license)

Just as I thought I was safe!

This announcement is at least overt, but I can envisage MS liberating applications that are not obviously from that source that users are enticed into using - with privacy consequences.
