At the end of the day, is anyone really surprised that these platforms censor/filter content in any way? Where did the assumption of an un-biased platform come from? These companies are in the business of making money, as much as they preach about 'making a difference in the world', they will always default to whatever gains the most public favor and generates the most revenue. I am actually surprised by the statistics, I had assumed that less people thought they were being censored. Although this presents an opposite problem, if everyone thinks they are being censored then they can claim the real truth is being 'censored'. Biases will always exist when money is involved.
