It's only naive because you chose the naive interpretation, based on sentiment and you not understanding the massive difference between laws and a company's rules. Until you understand what they are, and who decides if rules are against the law or not, mentioning "profit", "scale", "market position", and "different rules apply" doesn't get you closer to the point.

I'll take it down a couple of notches to make it easier: HN could serve every user under the Sun and still be entitled to have a (perfectly legal) rule that says "Don't solicit upvotes". No amount of "oh but at their scale" will change that.

Apple, Google, Facebook, etc. or any company actually do not write laws (they lobby and bribe for them but that's a different can of worms). They just write their own rules for their own products and services. Those rules have to be within the law and even if common sense and current evidence may say they break the law, it's up to a judge in an antitrust lawsuit to decide.
