This isn't really about the invisible hand of the market, I was talking about a single company. It costs money to keep those models up, which DDG itself hosts. If we were taking about Google, for example, then I could see the argument since it is a monopoly and my line of reasoning wouldn't work.
I'm not trying to be troll as you accuse, I'm just trying to think from different perspectives and have something less sensitive to ideology.
We don't find out the truth by agreeing with everything that panders to our beliefs.
