Then you look up what the actual regulation says and it's hundreds of pages of pure legaleese (over 100 pages for GDPR, over 300 for Online Safety Act), that you'd need to hire a team of lawyers to parse and interpret to make sure you're not breaking any of the regulations therein.
The first 33 pages are reasons why the law needs to exist. 23 pages are instructions for EU member countries and the EU itself.
The remaining legal text itself is spaced out more than any high school teacher would ever allow, and IMO it's also quite light on the legalese. Not enough that I'd feel confident to skip the legal department in my multinational, but it's far from the unreadable mess people make it out to be.
The OSA on the other hand... I'm glad I don't personally serve the UK.
