Deplatforming was always a bad idea that puts fundamental freedoms at risk. Now that it has come to telecoms, something has to be done to denounce this trend and stop it. When large privately-owned platforms (e.g. Twitter) or low-level utilities (telecom companies) take action to censor information, it has the same impact and carries the same risks as a government doing it. It stifles expression, exchange of ideas, and imposes personal morality on a broad set of people.
Twitter is the modern day equivalent of a printing press, they can choose to print whatever they'd like, or not - trying to liken them to a common carrier is in my opinion absurdity.
