It's pretty clear that you only draw your conclusions from a predetermined trust in Kagi, a brand loyalty.
The CEO is good, therefore when he moved a public conversation to a private Discord server, anything he says about the private conversation is now true, and anyone who disagrees with him is a liar.
Kagi Corp is good, so feeding data to it is done in a good way, but Facebook Corp is bad so feeding data to it is done in a bad way.
Kagi's efforts to show you only things you want to see are good, because Kagi itself is good. When Facebook does it, it is bad.
