While on principle I think this is bad, I think overall MS should encourage more users to switch away from Chrome. Chrome has +80% marketshare and quite frankly, Google is abusing their monopoly on the browser market willingly, otherwise they'd push for a more diverse market.
While this is quite the abuse of marketshare in OS to push Browser marketshare, I don't think the EU will care that much considering that Edge is a niche product, they will care once they do have a sizable chunk of browser marketshare.
It's an issue because of Microsoft's share of the pc market regardless of their share of the browser market. Its abusing a monopoly that is an issue not how successful this abuse is.
In the EU how successful the abuse is does somewhat matter. The EU doesn't like it when you have two monopolies and use one to reinforce the other. They're generally fine with leveraging one to get an advantage in another market space as long as you don't fall in the above category, ie as long as you aren't a significant portion of the market.
I do sort of agree in this case because it creates more competition in the market (ie Chrome vs Edge) which is healthy.
