Watch some of his videos. He has a lot of insight about the subpar quality of Apple devices, about the outrageous lies of Apple Genius Bar quoting people thousands of dollars for repairs that take him 5-10 minutes, for apple’s efforts to make the devices non serviceable, withholding schematics, controlling access to replacement parts etc.
In my mind, it makes sense that Apple won't repair a device that has signs of water damage without replacing all potentially affected parts (the bit about humidity is a discussion all on its own). Water damage can surface in a myriad of ways, and the last thing they want to do is charge a customer for a fix, only for them to come back demanding a refund because their device is broken again.
Rossmann has a small enough operation that he can handle this on a case by case basis. Apple operates at scale, so the fact that they have blanket policies like this makes sense.
Of course the debate changes when Apple makes it so that you can only use them for repairs.
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.
Here’s a televised CBS report.

He is extremely good at repair while despising the company’s despicable practices - and warns people about them.
