The problems this guy has with Apple are things still going on now.
Your comparison is equivalent with "one time long ago cotton was picked by slaves so I won't wear cotton".
That is irrational as its not happening right now. But the horrible apple conditions are alive and well.
Every problem the author notes in this article is specifically with Steve Jobs' behavior, not Apple's. I'm commenting on what was in the submitted article.
However, you reiterated my point beautifully with your cotton anecdote. I'm not sure why you needed to repeat the sentiment but, yes, it's similarly irrational.
