The very question that is asked is a straw man argument. Nobody is saying that Experts Exchange did some great evil (ex: genocide). What they did was build a business model based on taking from many and giving to nobody. Then to preserve that unsustainable business model, they used various underhanded search engine manipulations.
To me, they were jerks. When Google came out with the ability to filter domains from your personal results, they were the first (and only) domain I added.
Even to this day, they will show you the answer if you scroll through 5 pages of gunk. They didn't do any "great evil". They're just slimy and I get a bad taste in my mouth anytime I think about them. But at least they added that hyphen to their name at some point because for a while I couldn't NOT see it as ExpertSexChange.com.
