As much as I don't like the current rules either "I never got a notice until recently" is a very different thing than "It was fine until recently".
It was fine until recently. Crossposting another reply: > We've had the capability to detect audio for a long time. What changed suddenly in the last few years to deploy/enforce this at scale? Certainly not any improvements to detection. I've made a whopping total of $46 in something like 12 years on these platforms.

If a new automated speed camera catches you on a road you've been speeding on for 7 years it doesn't mean speeding used to be fine it means you'll now receive consequences for doing things which were never fine to do! It also doesn't mean the speed limit always used to be the current value or anything like that. This is because "when regular enforcement began" has no causal relation one way or the other about what used to be fine or whether that was different than what's fine now. It is only an effect, one where "what was fine changed" is only one possible cause.
