Whether it's "right" depends on the goal of course, but in this case I'm not understanding your point because nobody is prosecuting those companies for doing this.

In any case, these kinds of blanket statements are not very useful, because each case tends to be judged on its own merits. For example, yes, enough people believe that monopolistic tactics are not "right" and laws reflect that.

But the goals are clear in this case, no? The regulator said "do X the way we tell you to" and the regulated decided to do Y instead in order not to break the regulation requiring them to do X in a certain way.
