I took it as read that a company can take action to protect itself ie make business policy.
Another way of looking at it is US Communications Act section 233 (IIRC). US platforms use it to say "we're a platform not a publisher" to protect themselves from legal liability for the content that they "display" and "not publish" yet they make editorial/publishing decisions on that same content. So the government should be suing their arses off.
But of course lots of things "should" happen that don't. We know all about that.
