Is there a name for the type of government where the government pursues consumer protection, antitrust, etc policy by directly running one competitor in every important industry, instead of making rules for every participant?

Why would you expect this to work? State-run enterprises are not exactly great vehicles for creating competitive pressure

Depends how big the market is as well. Here in lil'ol Aotearoa pretty much every major vertical is dominated by a two player oligopoly, with the rest left to fight over the crumbs.

Sometimes govt has had to intervene and operate a state-run lowest common denominator competitor to ensure service provision for under privileged population segments - for example Kiwibank is largest NZ-owned bank - 85% of market Australian-owned.

IMO there are lots of opportunities for values-aligned states to actively collaborate, sponsor and curate open source tech competitors to maintain sovereignty and agency over Big Tech default option.
