Fair concern. On the other hand nobody uses Edge on Windows 10, do they? In my limited experience users seem to still use IE or go to Chrome or Firefox.
Edge is brand new, and foolishly branded to look like IE, this might stop average users who know about getting Chrome from using it. But it shouldn't. It's extremely rare that I'm forced to swap over to Chrome. Mostly I use Chrome to keep my invasive work IT staff from having access to my private browsing info.
