Chrome has won the last years on desktop. Is it really helpful to develop the own browser based on the Chrome-Browser? Why not using just Chrome? Maybe it's a little bit political and also a problem with the license... I don't know.
The new version of Edge is much different from the versions before. Chromium was developed by Google.
Not anybody will get the new Web-Browser for the Windows 10 OS. The update for the new version of Edge is available for the users who are running the Windows-Versions 1803 or 1809.
Important for the developers out there: The old version of Edge is not able to run after the users upgrade once! Hopefully the massacre with the compatibility of browsers in the frontend-development will end.
