I fully agree on this and I would also like to add the attack vector of being registered as a purchaser in a vendor database, which can be even worst if you define your home address as delivery address.
With a #seedsigner or #krux DIY hardware signer, buying the hardware elements from different vendors is completely impossible to really link your UTXO's with any hardware wallet/signer.
Theae last (HW vendors) have created a unnecessary need for the only own interest: their fucking business!
