These kinds of posts really bug me. Users don't give a rat's left buttock whether the "ecosystem" is closed or open or anything in between. They want something which works well and lets them buy stuff they want. Simple observation of consumer behavior has shown over and over again that people
simply don't care about whether their stuff is tied to Apple or Google, or whether their location is being tracked by Twitter or Verizon, or whether they'll have a difficult time moving their music to a different device later on.
If this was written as another post trying to convince developers to avoid developing for closed ecosystems it wouldn't as bad; evangelists can be a good thing, even if he's fighting a losing battle. However, as this post seems to be geared towards consumers, it's almost completely pointless ranting.
