Of course it’s silly but now there are data privacy laws everywhere that prevent a large company that makes money from just pressing “international release” and forgetting about it. Seriously.
Well sure, but I'm talking about country-specific laws. Like in Canada you have to follow some strict rules requiring you to inform users about how your software updates itself and receive consent to update at registration time. In China the laws about sending automated SMS are more strict. GDPR considers IPs PII when the rest of the world generally does not. CCPA requires statements about how you use consumer data to be present during registration. And so on.
Basically, different jurisdictions recognize different individual data and privacy rights. Sometimes the requirements even conflict. It's not obvious that there is some universal way to treat data that is acceptable by all, nor what it would be if it did exist. Cookie banners are an example of this going horribly wrong. EU wants to "protect people" online so they require websites to ask consent to use cookies when every browser already allows users to configure cookie policy defaults and on a per-site basis in the settings. Everyone interpreted GDPR as some big movement towards user privacy and adopted cookie consent banners for all users as the "right thing" and the world is worse for it. EU is backpedaling on the banners. Multiple browsers offer features that block them outright.
