If only they spent four years educating users and spending even a fraction of time at their press conferences to mention the issue. They have made almost zero effort to explain this to end users. You know, the people who will have their paid for apps broken.
Yes! They should have actually gone a step further and made it clear on the app store (from 4 years ago or whenever)whether an app was 32 or 64 and a caveat warning the buyer that 32 bit apps would be discontinued in the future. That would probably have prevented many people from buying them in the first place. It would also have put pressure on the developers to make a 64 bit version to increase sales.
