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 moves past being just your experience when you add in the bit about "I always assume when I hear of people with this problem that they're disrespecting their hardware by jamming it in doors / desks or perhaps have pets that chew on them."

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.

That's not a direct quote of that I said, the sentence I wrote is phrased in the past tense with the intent (and you'll just have to take my word for it) of surprise and / or previous thoughts on the matter up until the time of writing it. When you quoted me there you actually changed the construct of the comment to become an argument or judgement which was not the intent.

Fair edit and comment on my own, thanks for the clarification.
