Is it possible that you (and people you have spoken to) have more disposable income to buy entertainment than they have time to consume that entertainment? People above that line are happy to spend more money to save even small amounts of time.
People below that line often want to pirate, to allow them to spend their money on other things.
Possibly, although I wouldn't say it mattered. £2.50 can hardly be classed as a huge amount of money. The benefit of paying that amount vs waiting a few days and getting a version that's below in terms of quality is pretty obvious.
