"you can't cure gayness"

"of course you can, otherwise Apple wouldn't have approved an app that does it"

'Apple' is a name that carries authority and that can be used to lend credence to misinformation. That definitely does hurt people. Read the above as the last thing a father said to his gay son. If banning this app prevents even one tragedy, then good riddance. There are no disadvantages to applauding Apple for removing this app.
