Pandora, Spotify share the same fate. The entire world is not buying iDevices. Well, it's a small portion actually. So if they also focus their energies to lesser worlds maybe they have a better chance and if they make it a point that "no, we are going to cater to the class only" then they will have to compete against Apple on Apple's turf and within Apple's rules and laws and one fine day Apple can simply them to get out which it has done before.
Instapaper might be killed actually depending upon how many Mac users actually use Safari as their full time browser. I don't know any and among the people I know - pocket and Pinboard are the services they mostly rely upon and this kind of service(Instapaper included) are not much dependent on Safari either.
I don't really think any app or service is going to be killed until and unless they become totally dependent on iOS and OSX and I don't think there's any except like Instashare.
The author either assumed there isn't an ecosystem without an i in their names or with an X in the end; or it was directly towards iWorld which despite of being a MBA user I am not a member of.
