> by submitting as app, you submitting all your codes to them. think about it. remember there’s one of the most popular apps you want early days on app store was called ‘flashlight’ now see what happens? apple just incorporated that feature in iOS. so are building apps sustainable to a startup? maybe not.

I think it’s pretty clear that Apple didn’t need to plagiarise some dude’s flashlight app code to build their own version, and you don’t submit your code to Apple/Google anyway.
