A search engine index is an economic exchange between the website and the publisher.
To massively (over)simplify the argument to its essence (and ignore other important points): the publisher goes through the trouble and expense of creating the content
The publisher then allows its content to be copied by a search engine only because being shown in search results gets it traffic back. The traffic it gets in return has value, and the publisher is happy for this arrangement to continue as long as the value of the traffic is more than the cost of producing and serving the content.
Brave offering a "license", for its own financial benefit, to "allow" others to use the content for LLM training gives zero benefit to the original publisher. This is why I use words like "sleazy" to describe Brave's position.
This argument applies to Google and Microsoft. Right now both are failing at citing sources in their generative AI search results. That is terrible and I hope it's fixed soon, as otherwise they're being sleazy scrapers as much as Brave is.
Finally, I wholeheartedly disagree they what Brave is doing is for the "greater good". The fact they charge extra for the "license" to use the content for LLM training shows that.
There is a a difference between a human being able to access content vs a search engine indexing it (and in the case of Brave, "licensing" it on).
I share your concern about Google having this much power, and I'd add that Microsoft Bing is equally bad but gets away with it because they're smaller. Still, the final decision about which search engine indexes a website is purely the publisher's.
This is explained more in the article I referred to, but briefly: Brave delegates crawling to normal Brave browsers, so it's a huge IP addresses pool, not a single IP address or range.
Also, these search crawls by the browser do not identify themselves beyond the Brave standard UA header, namely a plain Chrome user-agent string.
That would be bad, and it is already bad that Google and Microsoft control so much of search queries, but the decision about which search engine indexes a website is purely the publisher's.
The major problem with Brave search is their position about indexing and licensing content against the wishes of the website publisher. Their robot does not identify itself, meaning the publisher cannot use the standard robots.txt to block its crawling if the publisher so wishes. Incidentally, the robots.txt file has been used in court cases litigating if a search engine is legal or not.
Even worse, they state that Brave search won't index a page only if other search engines are not allowed to index it. It is morally not their right to make that call. A publisher should have full control to discriminate which search engine indexes the website's content. That's the very heart of why the Robots Exclusion Protocol exists, and Brave is brazenly ignoring it.
Even worse than that, the Brave search API allows you (for an extra fee) to get the content with a "license" to use the content for AI training? Who allowed them the right to distribute the content that way?
