Okay, so what effect does Edge moving to Chromium have? If you didn't care about Edge due to its marketshare then why does it matter what engine it uses?

There are still millions of Windows boxes so in the future there could be millions of Edge users.

If Microsoft doesn't completely fuck up privacy again there won't be any more reason to switch to Chrome.
