> The cost of an uncharitable blog post is potentially unbounded (as in: not many people in a large tech company would know how to put a ceiling on the cost), and the cost of a bounty, even a high one, is more or less chump change.
Look up "apple bug bounty" on Google, or any other search engine of your choice, and you'll find absolutely no shortage of people complaining of issues with the program. If these complaints each cost Apple a bajillion dollars, then why haven't they shut down their program already?
Or, if almost all of those complaints are just from the reporter being dumb, then how are potential future reporters (who would care about the company's prospenity to pay) supposed to find actual meaningful complaints among the noise?
I don't think that sporadic blog posts are nearly as powerful as you're making them out to me: my intuition tells me that the company can usually ignore them safely, short of them making front-page news.
