True, It can happen on any platform, but at least you will get time to improve your app + add new features + fight with biggies while they are trying to copy from you.

On facebook and Apple they will just kill your app in a day.

but you can still get people to your site through any means (not just Google). If you build a Facebook or Twitter app, and either of those companies compete with you, change their apis, ban you, your company is pretty much finished.

This is why I don't waste any time writing those kind of apps.
