We should not have to google something like that in advance.
It’s obvious that many people were taken by surprise...
I highly doubt the billions of Google searches are after the fact research. I'm sure most are in fact advance research.
To me, it's obvious people don't pay attention to an email coming in that offers a chance to reverse their decision for 2 weeks.
Hardly Draconian. The consequences of your actions were made available to you in advance. That you feel one shouldn't have to Google such a decision notwithstanding.
A 14 day option to reverse your decision was offered. That you don't feel this is appropriate notwithstanding.
As much as you do not wish to hear it.. you could have avoided this.
Getting to the feature in question... a large number of contributions here are from those do not understand how 2FA actually functions. They mistakenly believe they need 2 devices. They complain of how long the verification process takes.
Going forward, Apple is not likely to move backwards and will likely tie more iOS/iCloud/macOS features to 2FA which may make resistance even more futile.
