The point isn't that it can't be regulated. What the original comment said was

> This is pretty easy to solve. If you present data by algorithm, you are no longer an impartial common carrier and are liable for the content you present.

But this is not in fact easy. It's hard to define what "present data by algorithm" means in a coherent way, and it's hard to extend liability for the content you present to liability for the manner in which you present it. You could make it work, if for some reason you really wanted to, but it's easier to pursue the strategy described in the source article of regulating specific abusive patterns.
