The “lens” feature isn’t mentioned in either Kagi manifesto.

So? It exists, unlike the vision in the manifesto. Since the manifesto can be interpreted in many ways (despite what you might claim), I think this feature can be helpful to show the Kagi intentions, since they invested work into it no? They could have build data collection and automated ranking based on your clicks, they didn’t.

People just submitted it. I don’t know why. They “trust me”. Dumb fucks.

Not sure what the argument is. The fact that people voluntary give data (for completely different reasons that do not benefit those users directly, but under the implicit blackmail to use the service)? I have no objections anyway against Facebook collecting the data that users submit voluntarily and that is disclosed by the policy. The problem is in the data inferred, in the behavioral data collected, which are much more sneaky, and in those collected about non users (shadow profiles through the pixel etc.). You putting Facebook and an imaginary future Kagi in the same pot, in my opinion, is completely out of place.
