Huh? How exactly do you package privacy? It’s something you can lose, but not something you can buy.
Kagi is selling search, same as Google. The difference is that you can only pay in dollars, not data.
I agree it’s overpriced, but this is where we are. The actual market for genuine web services is atrophied after 30 years of neckbeards naively insisting that web services should be free. Search should cost $5/year by now. But oh well, 30 years too late is better than never.
