I think it’s very fair. Anubis generated a lot of buzz in tech communities like this one, and developers pushed it to production without taking a serious look at what it’s doing on their server. It’s a very flawed piece of software that doesn’t even do a good job at the task it’s meant for (don’t forget that it doesn’t touch any request without “Mozilla” in the UA). If some security criticism gets people to uninstall it, good.

I'd say it's probably worse in terms of scope. The audience for some AI-powered documentation platform will ultimately be fairly small (mostly corporations).

Anubis is promoting itself as a sort of Cloudflare-esque service to mitigate AI scraping. They also aren't just an open source project relying on gracious donations, there's a paid whitelabel version of the project.

If anything, Anubis probably should be held to a higher standard, given many more vulnerable people (as in, vulnerable against having XSS on their site cause significant issues with having to fish their site out of spam filters and/or bandwidth exhaustion hitting their wallet) are reliant on it compared to big corporations. Same reason that a bug in some random GitHub project somewhere probably has an impact of near zero, but a critical security bug in nginx means that there's shit on the fan. When you write software that has a massive audience, you're going to have to be held to higher standards (if not legally, at least socially).

Not that Anubis' handling of this seems to be bad or anything; both XSS attacks were mitigated, but "won't somebody think of the poor FOSS project" isn't really the right answer here.
