In the US system of law, it is based on codified "rules". If you follow the letter of the rules you are fine - no fines.
The system of regulation at play here is the EU digital markets act. These laws are based on the effect of your actions, not the specific actions you undertake.
If the effect of the steps you take produce unacceptable outcomes, you pay fines even if you follow the requirements. The converse applies as well. If you ignore the rules but the outcome is in the spirit of the laws, then no fine.
The idea is to avoid malicious compliance but the cost of this is ambiguity in interpretation and also the market response to your actions might be genuinely surprising.
Here is a technical example to highlight the problem:
Apple were asked that you should allow independent browser technology implementations. They did this (to allow Google's technology to be employed as an example). But due to practical complexity they could not make progressive web apps work on iPhone (since they would need to route through the API which can be provided by Google's browser technology). So to comply with the rules, Apple disabled full screen PWAs and instead allowed them instead the web view area inside a browser, not full screen like a native app is experienced.
The EU regulatory body said revert that, and allow PWAs despite their own rules being then violated (as it would be using only Apple's browser technology) because the effect of allowing PWAs is a competitive marketplace for native app alternatives (web apps).
