So it is not a symbiosis per se but rather complete overtake of host (State).
State becoming irrelevant makes politics a reality show.
Though you could say that protectionism benefits a lot of companies, but a decrease in it would benefit more (and bigger ones).
It's really obviously symbiotic if you look at any level of detail.
Old leftists see it as corporations taking over the state. Conservatives see it as the state taking over corporations. Meanwhile, it's extremely obvious that both are complicit and that they grow to rely on each other in quickly inextricable ways.
This article is about Google doing police work: surveillance, analysis, investigation. It is only one example, a detail within a larger framework. Now, privacy focused competition represents an interference with critical police work.
Meanwhile, Google is highly involved in drafting legislative detail about how copyright is implemented. How liability for platform usage is implemented. Etc.
The state is not irrelevant at all. Politics might be a reality TV show, but that's always been the case.
But this is false. Corporations are and always will be exclusively answerable to their shareholders. Whereas the state can have any loyalty depending on who is controlling it
Shareholders are pretty happy under a system in which the corporation benefits from tax breaks and loopholes, fat government contracts, favorable legal environments, carve-outs for regulation exemptions, regulations that make entry into existing markets prohibitively expensive, etc.
