Well but as far as I am aware Lemmy has no fiduciary responsibility, as it is not a corporation, is open source and uses a web standard to communicate. Therefore there is no requirement for instance server managers to use the “official” version of Lemmy and could refuse to implement anti-user features, like specific app requirements. So I would say it would be really really hard to enshittificate Lemmy, if not borderline impossible, because users would just use their own fork, which would still be interoperable.
