If Kagi keeps charging, it will never be popular. They could lower their price to $0.99 a year with the same result. And that's a good thing.
That's arguably a good thing since a premium model mitigates the temptation of ad or data selling based approaches. But the fact is many don't care nor mind those as long as they aren't extremely intrusive. Even if they are (full page banner ad with small x), they may tolerate it anyway.
Kagi v Google, in terms of "How do you operate as an organization wrt the world?"?
Kagi wins hands-down. I couldn't care less about the privacy angle, the QUALITY is amazing. It's like traveling back to 2008, and for $10/mo that's a sweet deal.
