I expect a lot of people saying trust. My reason is simpler - a browser is not like an email service, it's not like an IM, it's not like a social network, not that these as FOSS wouldn't be better, but a browser is literally the most fundamental end-user software to access the Internet and I don't want to bother spending even 10 mins to support another browser that is not FOSS. This sounds harsh but I am not shitting on Kagi or Orion. While I have not much positive views on Kagi Search either, I understand that and accept that and hence I acknowledge that, but the closed-source browser - nope! In some twisted way it feels like paying public taxes to build a private road. It's not a great analogy, I know, but that's the closest I could come to in terms of a connotation.
