Competition is important for maintaining a healthy marketplace. Any behavior that makes it harder for others to compete, reducing the amount of competition, is therefore bad. That's what anticompetitive means.
I don't think protecting trade secrets is sabotaging the competition though.
fwiw I agree with what you're getting at with your original response. maybe I'm arguing semantics.
the more I think about your point that this is just competitive behavior the more I question what the term anti-competive even means
