Perhaps an under-appreciated perspective – most of us don't come from families that were paid the sort of salaries we get; and consequently we are more likely to be irrationally stingy about money as a result of having grown up (relatively) poor. I know that $200/year is not a significant cost at my salary; but I do remember a time when that would have been totally out of reach for me.

And also there's the fairness aspect – do I want to be participating in a system where only rich devs can get access to good tools? Yes, I understand that the world is not fair and already works that way, but I should probably not perpetuate that system; and instead, make work pay for it.
