I addressed the first quote... whoever wrote it is in the frame of mind that Apple is an AASP. They're not, and they don't work like one.
I see - but it is hard to imagine that Apple would be displeased at a third party monitor replacement but fine with a RAM replacement when the RAM replacement fundamentally involves removing the monitor.
The crux of the video is hinged on the part in the video where he says 2 of his cronies drop the iMac Pro off at the Apple store and they told them they would order the parts and have them back up and running in a 'jiffy'.
Either one of two things most likely happen;
They went to the Apple store. Omitted information on what they did to the computer and were told the computer would be repaired.
They went to the Apple store. Did not omit information on what they did to the computer and were told the computer would be repaired.
At the end of the day it looks like once they saw Apple couldn't offer a solution and they couldn't get it fixed they used this an an opportunity to make a video which is now at 1.5 million views in a little over 24 hours(Money in Linus pocket while giving bad press to Apple). No matter how we slice it this not a good look for Apple since apparently 99% of the population does not understand the policy in these situations which is enough of a litmus test to say the policy is confusing and needs to be handled better since we are dealing with Apple Stores and AASP and situations where they can't get the parts because to order the parts they must have a tech with a special certification and the special certification does not exist....etc.
