This argument against "the proliferation of platforms like Twitter, Facebook, Medium, Google and many others" would be more persuasive if the surrounding page weren't embroidered with share buttons from Twitter, Facebook, and many others.
The share buttons load trackers from the social network sites that follow your activity around said site. It is not there for the user's convenience at all.
That's already an ethically questionable action.

Even though this might not be the strongest argument from a purely logic point of view, it can still be a valid critique on the author.
