His point was: "Why recommend Apple when they do the same thing?"
Your point about them using less space is irrelevant when the OP was taking issue with the very principle of misleading consumers with inflated storage claims.
A 16GB iPhone 5 has 13.6GB available storage space. That’s 15% less than the name suggests. If a 16GB Samsung Galaxy S4 has 8GB of available storage space, then that’s half of what’s being advertised.
