running 4-of-2 definitely removes the service dependency.
you highlighted exactly the "bug" i wanted to patch though: the collusion risk. if beneficiary A and B have a beer together, you get rugged.
the "live service" here acts purely as a time-lock. beneficiaries can't collude to rob you today because the 3rd shard isn't released until the dead man's switch actually triggers. it protects you from your own friends.
You should consider highlighting that this can be used for way more than crypto wallets. The seed phrase can be used to restore a GPG key, a FIDO2 authenticator including SSH/WebAuthn, etc.
I prefer to do a 4 shares / 2 needed for recovery.
I keep 2 on different storage media, 1 with a trusted beneficiary, 1 with a different trusted beneficiary.
This does mean that the beneficiaries can collude to rob me tho. But it is simpler than running & trusting some kind of live service imo.

Why not use Vaultwatden for this ? It has a built in dead man switch recovery system.
