You know the saddest part?
This is an iMac Pro, equipped with workstation grade hardware. So it's made for business customers, people that are gonna earn their living on the device. The way it works with other companies like dell, lenovo etc. Is that they offer NBD service, you request service and they come in next day with needed parts. Because for business customer, what is truely important is being able to continue working, regardless of if warranty is still there or not there or whatever. Cost of downtime often would outscale the costs of paid repair - so regardless of what it takes, you just want your damn computer back and running. You can't be out of business for 30 days so apple can figure out their shit.
"You had a huge overvoltage and your PSU fried? You're gonna pay but sure, we get you up and running ASAP. A piece of metal flew into your screen? You're paying for the screen but sure, we're there with a new one tomorrow." That's what a proper business consumer oriented company should react like.
Based on linus' case, apple is just unable to serve a business customer and they should stop trying to sell "pro" equipment and pretend they can serve pros. Because clearly they can't. With that shit customer service, they can put destroy someone's business.
