This isn't entirely a strawman. One of the things that pretty much all repair professionals seem to hate is dealing with hardware that people have tried to fix themselves, especially stuff dating from the days where this was possible, because it's a huge amount of work to try and figure out what they could've screwed up. Now every company with a warranty has to either put in that work or give no-questions-asked warranty replacements to people who damage the products they sell, and all their other customers have to pay for it.
