I have to agree with the sentiments regarding Kagi.

I've been primarily using Kagi search since signing up for the private beta in April. Today, without warning, I was suddenly unable to use it.

It seems that with the launch of the public beta today, I was immediately switched to the free tier and limited to 50 searches for the month! That limit was obviously reached within just a few hours.

Bear in mind that I've been using it as my primary search engine across all platforms for the past 1½ months and all of sudden my latest search result returns a request for payment..
