I don't see how a bad actor can "rug pull" when everyone has a different encryption key.

A cryptographic scheme weakness is a threat to all computing systems, it's not worse for FHE. It's just that FHE relies on newer encryption than existing widely deployed crypto.

The main use case for FHE is to enable partial data sharing between parties who are forbidden from sharing data with one another, or for whom being in custody of it is too much of a liability.

the reason I think the threat is worse for FHE is because it's going to be used to share encrypted versions of private information that isn't shared today, and realistically, the only people exploiting cryptographic weaknesses right now are intelligence agencies, where in the case of a repo of FHE enciphered PII shared with a vendor is suddenly decryptable by that vendor. my point is it's not the same as other encryption for those reasons.
