'Just asking' is a lot worse than following the legislative process. They are trying to use their influence to accomplish an effectively legislative outcome without oversight. This creates a dangerous gray area between law and intimidation. It's similar to when Visa, Mastercard, etc. were 'just asked' to stop dealing with Wikileaks. In fact, it is common for dictators and totalitarian regimes to rule through 'just asking' instead of law. Not a good precedent.

I think that statement includes an implicit threat of possible legislation action if necessary.

Apple complying with their request and passing legislation have the same outcome.
