I understand the issues presented here but I don't understand how a company with apples model can avoid this issue. You give millions of people access to an sdk for years and hope that no one comes up with some good ideas that you would want to bake into the OS. I can't help but feel that if it wasn't instapaper that was the victim this would be a non starter. What about all the mapping companies that have taken a huge hit from google. This is the way everything in the world works. If you have a good idea then the chances of it being improved upon or at least adopted by your competitors increases. It is impossible to decide either way with issues like this. What if instapaper was poorly written and slow? Would it be ok to replace it then? What if apple had thought of this years ago before instapaper and only just implemented it. I build apps myself but don't really have an issue with their policy. You agree to apples terms and conditions when you develop for the platform and you have a choice. I would wager that if we looked at most major features of the OS in both android and iOS we would find large parts of them have been stolen / adapted from other peoples ideas and work.
