The GDPR didn’t give a 6 month timeline.
And GDPR had a long transparent process that in addition to the official implementation time, gave companies a lot of time to see what sort of rules they would likely be working under even before it was approved.
The worst government since liberalization, however, makes capricious rules, without input or deliberations, drops them on the world like they are a JayZ album, and then gives atrocious timelines for compliance.
More often than not they will then backtrack on those rules once enough time has passed so people will forget how atrocious those rules are (like during COVID), or in some cases (such as demonetization), they will double down never mind the generational economic damage and direct death toll.
