Imagine apple cloud let you transfer your photos to google cloud via a button click. Is this lock-in?
In the world of Bitcoin, I believe the answer is yes. Because at any point apple cloud can refuse to honor your click.
Now, Bitkey has the Emergency Exit Kit for this scenario. But my complaint is that it makes a security trade off not made by seeds (and being able to export your key material).
A hardware signer that creates a wallet that no other type of wallet can recover is definitely a new way of thinking about security and, I believe, deserves a healthy amount of inspection.
While I enjoy marketing via controversy, it's not really "fud" when people react to the controversial statements.
But I take your points, especially the reality that self custody is not coming to Bitcoin in any great number and that we need good solutions for lots of use-cases.
