This article is pure crybaby bullshit PR about a nonexistent problem. Does anyone care about DDG anyway? They're trying to solve a completely imaginary problem, and they haven't got a hope in hell of creating a viable search engine as that costs billions of dollars. Why is this article even on HN?
1. Does anyone care about DDG anyway? I think it's safe to say, yes, there are some who do. I for one.
2. The problem DDG is solving is imaginary. Oh really? What precisely is that problem? Is it search itself that you're referring to, or the prospect of going up against Google? If the former, then you are delusional, and if the latter, there is nothing wrong with attempting to disrupt a monopoly.
3. A search engine costs billions of dollars. Actually, no. There is no rule of computer science that says that. If someone discovers a new, cheaper way to do search then cool!
In answer to your final question, perhaps the reason this article is on HN is to inspire comments like yours, which are wrong, and then comments like mine, which correct comments like yours.
