If you read this article, the author is basically saying “the way this worked before was very opaque and probably almost no one figured it out, but _I_ knew how it worked, and so the change is bad for me”.
Do they have a good point that they have a valid use case? Yes. Do they have the only use case? No. Did Apple do this to try to make things better? Yes. That doesn’t make them “evil”, that makes them trying to make things better.
Flat out removing a functionality that is 100% certain to be critical to many without any way of regaining it via any combination of features found on the iPad…
And without any notice whatsoever, and with no way to downgrade back, gets pretty close to flat out evil.
Don’t try to talk out of both sides of your mouth.
Even if they clownishly made it more buried and difficult to find under a dozen submenus… it would still be much less bad in comparison.
(If they never advertised or implied the iPad as being suitable for presentations, education, etc., then that have lessened the severity, but clearly that’s not the case)
