I've been using (and occasionally paying) Kagi on and off for a couple of years now. I truly think they're building something interesting and valuable! While I haven't agreed with every product decision they've made, the founder is very good at both understanding his business and also explaining their decisions. This is a well crafted explainer of the search business and the monopoly case-- much better for sharing with less tech-savvy peers than most mainstream media explainers on this subject!
Edit: wording
Edit 2: Can you imagine a world where Google's Internet Search Index is legally considered an "Essential Facility"!? https://law.stanford.edu/publications/essential-platforms/
