I'm not sure if this is going to make a difference ( #LLMs weren't able to read #licenses or terms & conditions before when these were not formalized in a "machine-readable" way (plus, besides licenses we already had the robots.txt declarative files; even if those were not as expressive as this new proposal).
So, is this extra work for web developers and maintainers? Are we going to operate under the new assumption that if we didn't do the work of implementing this then we are granting permission to scrapper bots to steal all our online creations?
Or can this be a net gain for creators in some specific way?
