"It can't be a coincidence that Apple's gesture also comes as myriad large developers make forceful complaints about the practises of Apple and the 30 per cent commission it charges devs."
So refreshing to see the correct use of "myriad" rather than the all too common and incorrect use such as "a myriad of".
Aside from that, I can't see how Apple can justify taking a 30% cut of App Store purchases when said store hasn't changed much in years and so ongoing development costs would be either very low or close to zero, unless Apple employs huge numbers of dedicated App Store-related staff?
They're just a greedy company who are willing to shaft both customers and developers, and they mostly get away with it because of the lock-in to their walled garden.
