While that's possible I would say that's extremely unlikely, so you're better off getting the feedback.

Think of this way, on the spectrum of loathing to loving your idea, they have to be on the top end and have either the resources or technical knowledge to execute, and now they have to pass you who has a hypothesis already and is looking for feedback. They don't know how much or what you've already gotten, so if they flat copy/paste based on what you've spoken to them about they could be heading off in a different direction. If that's the case they're not really competing with you because they're somewhere else in a different niche.
