Personally, I wouldn't think that the leakers were getting paid. Even if they were, I imagine the amount that these particular online web sites are able to pay is very much -- especially when compared to the average Apple employee's salary.

This makes me think that money isn't the primary motivating factor, if it is a factor at all.

option A: “I’m working on really cool / inconsequential shit. But I can’t tell you about it. Maybe we can catch up next year and I can tell you what I did”

option B: “I work at Apple”

option C: just stay home.

Also somehow I doubt that newsrooms are making enough money to pay $100,000 (or any money for that matter) for random tidbits about products that don't really matter in the grand scheme of things.
