Hello?
It's there to prevent money from being spent from that address right? But it can receive money right?
The freeze address or UTXO is on the software level, so if you have installed electrum on your device then it only works on a particular level but if you import the same wallet into a different device then you need to freeze the address or UTXO to make it unspendable on the device again. So yes, it's not possible for anyone to restrict an incoming TX to an address.
