Not sure what's what... but manufacturer does not have any sort of warranty service locations besides few R/D points. They use contractors. I am not sure why people especially from US treat RMA like being sent to ASUS or whatever like in 1950ties... its sent to a authorized service location, contractor and they decide for most cases what's what and if not they create internal tickets and communicate with ASUS. They do multiple brands and services, you cannot live these days by doing only one type of repair.
Also it is a paid job, what did you expect the labor cost is? A price of a shitty pizza? 50-100$ with VAT depending on where you are on the planet, we all pay taxes and that price includes logistics, call center support, transport etc. Then the other BOM items leave what? A ~100?
Well the sensational video is too cherry picked, even at the start they don't start from top of the list what are all warranty void reasons. They picked on the minor flaw. Considering the fact they have changed TIM on those, because they had to make a YT video about it, ASUS strictly prohibits that, you take apart the unit and clean, change storage, RAM for laptops without cracking clips and plastic, but the thermal heatsink removal is a warranty VOID cause. There is no reason to change PTM7958 on those, it is absurd.
Seconds there is no policy how to treat customer induced damaged units afterwards, that leaves that service location is seriously a monkey service. But that is because of poor consumer protection laws. Here we cannot ship dissembled unit back unless asked, it ships as it was. If you screw up, service location partner covers it. That's it, no sensation, no video. It has NOTHING to do with ASUS.
