Can you be more specific as to your claim? Not illegal in what sense(s)? And what is your basis for the claim?
I'm not a lawyer, but saying "violating a website's ToS is hardly illegal" is fraught advice.
While individuals may get some leeway when it comes to ToS violations (see [1] and [2]), I would expect companies scraping and/or extracting content would be treated differently.

Google Search results are definitely "public data" so long as Google provides them to anyone who asks.
Again, if scraping data from websites without permission, Google simply wouldn't exist. Bear in mind, robots.txt is a feature that Google and Microsoft choose to respect, but the default assumption search engines have made from the beginning, is that they are free to grab whatever they want from the web, unless you ask them otherwise to please not.
Which Google's robots.txt does.
> scraping search results isn't illegal, by any means
While scraping the results for yourself to look at might be OK, scraping results to display verbatim in another search engine without permission stretches fair use.
No, it doesn't, because Google results aren't copyrightable, hence, there is no such thing as fair use. It's just information anyone is free to collect and use as they see fit.
If a monkey can't copyright a selfie because they're not a person, an algorithmically generated spew of stuff Google ripped from elsewhere certainly lacks merit for copyright.
If I made a site that claimed to help you with your math homework and simply sent the queries to WolframAlpha, that would also not just be "scraping."
(But, again, there's a difference between scraping and echoing a request on another site and waiting for its response. The latter is basically unauthorized use of its API, not scraping.)
My guess is Google's "donation" is pennies on the dollar from what they benefit from Wikipedia, and more of a token gesture than anything else.
1. Redirection to Google.
2. Piping Google's results back to Brave Search's UI: https://news.ycombinator.com/item?id=27594754
The original commenter was asking about the latter.
