I don't know who thought this would be a good idea and what the use-case for Chromium Edge would be for apart from replacing the CharkaCore-based Edge. But I would like to know why to bring Edge onto other platforms when it is based on the same browser engine, JS engine, etc. Perhaps something like Office would be more beneficial to Linux users rather than another Chromium-based browser.

It's like Apple coming along and replacing the WebKit-based Safari with 'Chromium Safari' and pitching that to Chrome users. I'd prefer neither and keep using Firefox.

This tweet looks more like they are 'selling' Microsoft-branded igloos to eskimos and penguins.
