Not just cheaper.
. . ., but there's no sign that Apple's likely to budge on its longstanding policy of not paying for bugs
Ha. That's because there's no such thing as an Apple bug. You're holding it wrong.
Apart from the obligatory Apple bash: Of course they will all like crowdsourcing. No pensions to pay, no sick pay, no NI contributions and I bet it's tax-deductible as advertising costs as well. And instead of 1000's of CVs of mediocre, boring, freshly unemployed CompSci MAs you get a proven bit of work from someone creative who might be worth looking into.
Everyone (insert David-Tennant-type "well . . .") is a winner.
