I just wish they'd moved to Gecko instead of Chromium. It's not like Gecko is an inherently inferior engine by any stretch, and it would significantly bolster their marketshare so that developers actually have to test against it.
I think the biggest reason they went with Chromium/Blink is simply because of market share... most users at this point are using Chrome for better or worse, and MS is going with the safest bet in terms of user compatibility for today's web.
Sadly, that doesn't make it wrong per se, just deeply discouraging. It makes me think we're past the point of no return.
