Marco Arment joined in on the iOS subscription kerfuffle:
The root cause for so much of the subscription ruckus, I think, isn’t that 30% number — it’s that Apple pulled the rug out from under some major apps after the fact. And unlike nearly every App Store rule change in the past, this is a major change that developers couldn’t have been reasonably expected to anticipate, and it’s not based in any practical need for the health of the Store or the platform (malware, abuse, etc.).
This is one of the points I have been making. I think this move sucks so much because the rules are changing after they were previously established.
