Regulators take tip offs and if one gets through, the enforcement action is usually pretty fast and strong.

They also like doing this. The ACCC makes a huge deal out of parading their latest conquest in the media.

Has its faults, the ACCCs dealings with telcos are especially terrible.

I still have friends at an Applecare provider based in oz, and they had a big one where as a settlement with the ACCC over trying to have it both ways with consumer law, they agreed to provide repairs or replacements for like a decade of wrongfully denied hardware issues. Hushed it right up. It was in lieu of a public apology from memory. But my friends spent weeks calling back old customers, chasing new contact details etc, to try and get them all free replacements.
