I don't defend dark patterns, it obviously is one there, but your time is worth zero when you pay zero. The analogy would be free taxi drivers taking your to their kicking back spots first. If your time is worth X, spend X. It may prove a bit difficult since the paid search engine marketplace isn't thriving. How much would you be willing to pay for a search engine that only displays organic results? There are actually free solutions easy to set up to get that from Google results, but I'm wondering since you mention value of time.
