JetBrains IDE's is the most notable exception of dev tools I personally pay for, insane value and productivity makes it a no-brainer purchase given its instant ROI from time saved. Life's too short to not maximize your productivity for a few $'s.
JetBrains is a great example. People pay them because the product is by far the best and the cost is reasonably humble. I think it wouldn't make the same total revenue if they were selling it for twice the price.
To be fair, that's true of almost everything.
