The new bill reinforces that all data brokers must register with the California privacy protection agency, and it requires the CPPA to establish an easy and free way for Californians to request that all data brokers in the state delete their data through a single page, regardless of how they acquired that information. If data brokers don’t comply with these rules, the bill stipulates they be fined or otherwise penalized.
Hopefully this becomes the standard nation wide. Having a single page where you can delete your accounts on multiple services with a single click sounds like a data privacy dream.
The way laws usually work is (gross oversimplification):-
Different state, same country - they have to follow this rule when dealing with customers from California.
Different country - they can break the law, but then California / US can sanction them (i.e. no US-based company can directly do business with them)
There are workarounds to both but 99% of companies will just comply, at least on paper.
