How many other sites might have leverage to charge to be indexed?
I don't want to live in a world where you have to use X search engine to get answers from Y site - but this seems like the beginning of that world.
From an efficiency perspective - it's obviously better for websites to just lease their data to search engines then both sides paying tons of bandwidth and compute to get that data onto search engines.
Realistically, there are only 2 search engines now.
This seems very bad for Kagi - but possibly could lead the old, cool, hobbiest & un-monetized web being reinvented?
