Gruber has now spent about a week of writing fuming articles going after Chen because he dared to say the iPhone 13 feels like an incremental update. It's almost creepy how he tries to erase that (pretty harmless) criticism, and even for Gruber it seems too petulant. Gruber will always be an de-facto Apple employee, and therefore never be a trustful source on Apple, but it seems in his older age now he has lost the ability to hold himself back thereby creating a big "tell".
