I don't have a problem with them selling ads. I have a problem with the insidious tracking that has become a part of those ads. Mojeek sells ads but doesn't track you everywhere. Also, there's SearX instances, which typically don't sell ads or data.

They also don't use LLMs. If you think Kagi isn't giving away or selling your data, think again, because the LLM is doing it as a core function.
