Those are mature industries with more developed legislation and case law. Those precise rules that those companies should follow those companies are more defined and people who work in those industries, and their lawyers, can then be mindful of exactly what they can get away with (for good or ill), leaving less opportunity for their actions to go to court or political debate. Law suits like this are part of an industry maturing. They clarify open questions through court judgments, and sometimes prompt legislation that makes rules more explicit. It’s just how laws work.
