Leaving aside the misleading title, i am not sure how the $100k number was arrived at. Developer hours? cutting off one dedicated developer who fixed IE issues?
If you are catering to creative professionals, who are going to be using huge apple monitors and macs (66% of the site's users are on a mac), ignoring IE isn't going to be a big deal. Even many of those ~4.5% of IE visitors might be on IE9 /10 which are pretty decent browsers. I am not here to support IE, i hate it like every other developer who builds stuff for the web. Also, compete.com tells their approximate UVs for February was around 13k. Ignoring a small number of users here is not going to have a huge impact. If your are site/app with millions of users, then it will be a big deal.
PS: If you are building a hipster social network or a video post processing tool, ignoring IE is going to save you significant time but if you are catering to e-commerce/finance or any other common demographic even thinking about ignoring IE isn't wise at this point.
