Yeah, this is the part that makes the developer not just petty, but actually quite disingenuous and actively hostile to their own users.
It's one thing to argue against the policy and there's nothing wrong with that. But it's unacceptable and close to outright lying to imply that the policy decision makes the user's account only usable with Apple devices.
The really puzzling thing about all of this is that the developer's primary issue - he believes Apple is being hostile to developers - is exactly what he's doing to his end users.
Apple took away his choice, so he's taking away his users' choice to use the feature as they desire.
