Anubis isn’t really about reclaiming the public internet, though: it’s about excluding some internet users. It has its reasons, of course, but it’s fundamentally about making the internet not a commons.
While I get your point about Anubis excluding some users, its purpose is to protect the "commons" from those who would abuse and destroy them: big tech crawlers that do not respect robots.txt files.
From my perspective, anubis (and iocaine etc) is about keeping misbehaving load generators from suppressing small-scale "classic internet" sites. So yeah, it's exclusionary, like keeping semi trucks from taking shortcuts through a schoolyard.
