Do you think that all apps should have access to system events without asking permission? I sympathise with the frustration, and I agree that Apple could’ve done more to help less tech savvy users navigate the challenge of increased security. But every operating system is a series of trade-offs between developer convenience and having the system defend the user’s interests.
But if I was in your position, my response would be to do the best job I can to educate my users about this and hold their hand through the process as much as possible. If your competitors face the same challenges, doing this well could be a real competitive advantage.
