Re: They won't come just cause you build it
"The bigger reason, IMO, is that it's a Microsoft browser. Microsoft basically did everything they could to destroy the internet with Internet Explorer."
I don't think that's a reason at all. I'm pulling statistics out of my ass here, but the browser user base has multiplied many times since late 90s when MS killed Netscape, and "newcomers" are not aware of the history, nor do people even care about decades old stuff. If users were looking for a browser from an ethical company Chrome certainly wouldn't lead the pack!
Chrome is a solid, working choice that renders web pages very well. That's not the reason it is the most used browser - the reason is the (already mentioned) fly-by downloads at Java and Adobe product download pages, which are opt-out, and when the browser is installed it imports the IE settings quite seamlessly, and the less adept users won't even notice except that the browser launch icon has changed.
Edge can't gain popularity unless Windows 10 gains popularity since Win7/8 will never get it.
Edge was rather unfriendly to use back in 2015 when I tried it for a few days, and it got better when it got support for adblocking last year, but the UI just isn't as nice as my Firefox.
Lack of adblocking probably didn't matter too much since I constantly see business and home users using browsers with no adblocking at all, and they're not ever aware of such things.
