An additional perspective is that Rossman’s 5-min free repair cost Apple $1000+ in revenue.
Apple can totally scale repair but it won’t be as cheap and profitable.
So what they scale instead is lying to their customers.
The Genius Bar employee presented a lie as a certain fact. They didn’t say that there’s more to be found out, that humidity indicators are sometimes unreliable etc.
They went with the highest grossing lie.
That’s a policy.
Having such policies calls for legislation protecting the customer and giving independent repair some chance.
