I don't blame anyone if they don't want to support Edge/IE. Microsoft's browsers are horrible to develop for. Personally I'd be much happier if more of my users would switch to Chrome.
Having been a FF/NS/Mozilla browser user since the 90s, I know it's not nice to be treated like a 2nd class citizen. However, unlike the current Edge/IE users, I made a choice.
Not voting is a choice. Not educating yourself is a choice.
Choices have consequences.
