@BendingUnit @snarfed.org @seahorse passive is a technical, not emotional term. Alternatively an "active" bridge would be akin to a webcrawler, actively pulling in posts whether or not they're requested.
That is also a wild misuse of enshittification. Enshittification is when a platform or product offers an explicit feature and upon achieving market dominance removes that feature.
This is simply someone using the existing features and design of ActivityPub in a way you dislike. This is not being provided by any of the platforms involved and is not something added or changed about the ActivityPub protocol.
This is as much enshittification as complaining about platforms other than Mastodon using ActivityPub.
