It's not propaganda, it's my experience (and actually the guy sitting next to me at work as well, although he said his girlfriend has gone through a MacBook charger and her current one although working is looking tired but not broken yet).
It's fine to say you don't have issues, but if six other people are saying they have issues, and know people with issues, it's rude to write them all off like that.

EDIT: replacing the paraphrased quote to try to avoid unfairly representing the original statement and remove my read of its intent. I had paraphrased it down to ""I assume the people having issues are responsible for those issues" which dropped the bit about perhaps having pets or similar and so put everything on the disrespecting the hardware part.
