NSA gives info to the advocacy center where _US_ companies (think Lockheed Martin) can ask for assistance, e.g., get access to competitors bids for international contracts etc.
Nothing you posted contains any evidence that the NSA gives trade secrets to US companies (directly or indirectly) to increase their competitiveness.
What you posted is just the advocacy center's stated purpose--to help facilitate bids by US companies for foreign contracts.
I know the US government gets directly involved when dealing with companies like Lockheed Martin exporting military equipment. And I'm sure the NSA would share military secrets with defense contractors, but that is directly in their scope of mission to protect national security.
Stealing trade secrets to pad the bottom line of US companies is not part of their mission, and so far you've posted nothing to prove they are violating their mission in this way.
