If you feed somebody's posts into your shitty LLM without an explicit and reversible opt-in, you are violating the consent of fedi users.
This "Zeitgeist" app not only violates consent, but it also doesn't have a centralized ActivityPub identity that can be blocked or defederated.
The creator is making pretty clear that it's designed this way to make it harder to block.
Normally, you'd expect an LLM scraper to have a single (blockable) ActivityPub account doing the scraping.
This is designed so that everybody who uses the service has their identities harvested to steal people's data on the app's behalf.
