It’s not on Apple. They explicitly warn developers not to do this because stuff exactly like this can happen. If it were an issue involving public APIs, then yes, it would be on Apple.

I get it. I’ve used private APIs in some of my Apple apps. But when you do, you take on a certain level of risk and responsibility when you’ve got customers.

The bigger question is why none of these Electron app developers, particularly larger outfits like Slack, didn’t catch this issue in the last 3 months they had access to Apple OS betas.

Do they have a QA process? Perhaps they should start.

For all we know, they could have filed radar issues with Apple months ago.

They could have, but the most likely response is "Do not use private APIs. They are not intended/ready for third-party developers yet."
