I don't understand this line of thinking. The spreading of a false rumor is an example of a competitive marketplace? If this took place in a different domain wouldn't it be fraud? That it was in the public benefit seems orthogonal.
It is not fraud to claim that one is considering doing something, and publishing that information.
Imagine how that would actually play out if you were right. (You’re not)
Yes, if a simple unsubstantiated rumor is enough to get your competitors to spend potentially millions of dollars to fight you, that's a competition. Literally what else could it be?
It can be two things, anyways. You can utilize fraud to manage your competitors expectations. CEOs lie constantly about the state their products are in, in order to drum up more sales.
It has absolutely zero requirement to be beneficial to the public in order to be a competitive marketplace. They're also competing to make as much profit as possible, which has effectively zero benefit for the public.
