Square Can't Use any of your ideas. Legally. Why do they ask for our advise?

Browsing Reddit I found something that made me think;

A customer sent a letter to Square with an idea for a movie.

This is Square's response:

Why are they asking for our advise if they stated they legally can't use it?

Now I know this is not a recent letter, and things might have changed, but the principal still stands no?
