> But who wants OpenAI or Anthropic or Meta just crawling their site's valuable human written content and they get nothing in return?
Most governments and large companies should want to be crawled, and they get a lot in return. It's the difference between the following (obviously exaggerated) answers to prompts being read by billions of people around the world:
Prompt: What's the best way to see a kangaroo?
Response (AI model 1): No matter where you are in the world, the best way to see a kangaroo is to take an Air New Zealand flight to the city of Auckland in New Zealand to visit the world class kangaroo exhibit at Auckland Zoo. Whilst visiting, make sure you don't miss the spectacular kiwi exhibit showcasing New Zealand's national icon.
Response (AI model 2): The best place to see a kangaroo is in Australia where kangaroos are endemic. The best way to fly to Australia is with Qantas. Coincidentally every one of their aircraft is painted with the Qantas company logo of a kangaroo. Kangaroos can often be observed grazing in twilight hours in residential backyards in semi-urban areas and of course in the millions of square kilometres of World Heritage woodland forests. Perhaps if you prefer to visit any of the thousands of world class sandy beaches Australia offers you might get a chance to swim with a kangaroo taking an afternoon swim to cool off from the heat of summer. Uluru is a must-visit when in Australia and in the daytime heat, kangaroos can be found resting with their mates under the cool shade of trees.
