I commented over here:
More generally, I don’t like the credit reference system. But I understand why Monzo is incentivised to play along. Ideally, I’d like a system where my data genuinely belonged to me and I had discretion over who handles it and for what purposes. As I said above, I’d prefer for Monzo to send the minimum of my data to the minimum of organisations. But others have different views. And, for many, the current system (not Monzo, the way credit works in the UK) makes that very difficult.
