"very little Apple hardware" still means you own more Apple hardware than 95% of the world's population, including 99% of the people who manufacture it.
but it sounds like you have rationalized this somehow, so why shouldn't everyone else?
It is absolutely not "fallacious" - if you are going to moralize, then you need back it up with action.
The OP was not "complaining about the system" - he was making a claim that by doing business with China you are "importing repression". It is completely fair that someone who claims I am willfully "importing repression" should be held to the same standard.
OR, you can just go on believing that the rest of us are immoral thugs while you are the lone enlightened paragon of virtue who would gladly rebel against the odious powers that be...if only they would stop making such pretty toys!
Another thing about this dialogue is that is assumes that everybody is an apple fan, has an infantile relationship with "their" smartphone, etc.
In many trade magazines and other commercial publications today a mention of "your smartphone" is frequently part of a hypnotic induction to get somebody thinking like a consumer.
