I assume you're asking this in good faith, so I'll answer in good faith.

Laws vary from country to country, state to state, and they vary tremendously. Laws are also changing all the time. There's literally no way to predict what rules will be in place at any given time.

Also, adding code to meet some government regulation takes time and effort that (form the company's perspective) could be better spent building a product and making money. No one would "choose" to implement some random compliance rule unless they're forced to.

Because of move fast and break things mentality. Let's say if ChatGPT was launched respecting GDPR, or respecting copyrights, they would have reached nowhere.
