ADDENDUM 1/2: Kagi is apparently now flailing around trying to find a quick and dirty fix for the uproar: “maybe you can disable Brave in your search results or we’ll try to make their services free other something” etc etc.
My deal-killing objection was not actually them using Brave’s services, but rather their •unwillingness to think• about the underlying issues in doing so. I can’t say that this “we’ll let you cover your eyes too” sort of response addresses my concerns at all.
