> So that the consent agreements and cases arose as a result of antitrust regulations is true. But when you say "the legal theories of when and how to apply antitrust regulations" has changed, that is not supported by the consent agreement because those agreements are not enforcements of antitrust regulations.
You seem to be implying complete independence between something being the results of antitrust regulations, the results of the enforcement of antitrust regulations, or the consequences of theories of how when to enforce antitrust regulations. For people who speculate that these three things might be related to each other, your argument will not work.
