Honestly, the character is the worst part about it, but that can be changed with an enterprise license

The Javascript requirement is not ideal, but the reality is that the vast majority of the internet already needs it, so I don't see it as that much of a hurdle. The other problem it has is that it requires a sort of herd immunity to achieve the goal. If a critical mass of websites don't use it, then the AI companies can simply just pay for the increased compute costs for the sites that do.

In a world where more than half of websites that are being scraped had some kind of protection like this, it would work much better.
