Everyone deals with these type of customers. Product sellers, repair shops and yes that already includes Apple. And even if Apple was currently magically immune why do people want to protect the most profitable company in the world from something everyone else deals with?
> And then someone will mess up the repair and blame Apple for a malfunctioning device or demand they fix it for free.
I call this bs. Apple doesn’t want devices repaired because they are too greedy. Their own repairs in store are sometimes more expensive than buying new. Guess why that is? Pure greed.
