> Yeah it seems pretty clear that this was a 1Password flaw and didn't really have anything to do with Substack's UI The UI is styled to make it so that a form input is completely indistinguishable from surrounding text, to such an extent that even people who know it's a form input in this thread have incorrectly assumed that it's not manually editable. I can't comprehend how anyone could defend deliberately misleading UI design in a form that is asking for your credit card information. This is a problem with Substack. 1Password can definitely do better to guard against it happening, but the only reason it did happen is because Substack actively tried to hide important information from users in a payment screen.
