What do you mean, "anti-competitive"? There is no rule of competition that says you need to reveal trade secrets to your competitors.
I do think it's sort of unproductive/inflammatory in the OP, it isn't really nefarious not to want people to have easy access to your secret sauce.
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
I don't think protecting trade secrets is sabotaging the competition though.
and google gives everyone the possibility of being excluded in their results.
