In saying that different administration priorities and changes in political support for tech drive anti-trust actions you are making my point (which I maybe didn't make clear). That kind of arbitrariness means firm's counsel can't say "don't do X" like you want them to. Because "X" shifts. It also means counsel sensibly focuses on appearances, since appearances can be the main driver of political support.
