As the wikipedia page you yourself are citing, overturned on appeal.

> And ongoing: United States vs. Google LLC (2020) [1] and United States vs Google LLC (2023) [2].

Ongoing, so a bit hard to count these as evidence of successful market regulation.

So the law says "Don't do behavior X", the government takes you to court, there is a judgment, you appeal, and win the appeal.

I'm not sure "dismissed on appeal" means "this isn't working as intended".

Successful market regulation includes investigating issues, prosecuting them where there is reasonable grounds to do so and it also includes a determination (either in investigation or in court) that something is not an issue.

Overturned on appeal but MS was fined heavily over the years using the same justification. The one I remember off the top of my head was the WMP fine[0].

If you have an OS, everything within should be open for competition and courts have generally ruled as such for years.
