As you say though it's only shared to any other instance listening. The point of consent-based federation is that you get to choose which instances do and don't get to listen. So if your comment hasn't been sent out out to other instances, they don't have it.

What's stopping malicious actors to create an account on the same instance as you and follow you (or your RSS feed) exclusively to pull your data?

Remember "information wants to be free"? That adage works both ways. If people want (or need) real privacy, they need to be equipped with tools that actually guarantee that their communication is only accessible to those intended to. The "ActivityPub" Fediverse is not it. They will be better off by using private Matrix (or XMPP rooms) with actual end-to-end encryption.

Agreed that people who need strong privacy should use something like Signal (or maybe Matrix or XMPP). And also agreed that RSS feeds are a privacy hole on most of the fediverse; Hometown and GoToSocial both disable them by default, Mastodon should do the same.

Nothing prevents malicious actors who want to make enough of an effort from creating accounts on instances (or for that matter Matrix chat rooms). But that's not feasible for broad data harvesting by Meta.
