Twitter admits during 2016 election Trump used platform half as much as Clinton but had twice as much success. Additionally, Twitter legal counsel admits to hiding up to 48% of negative Clinton twitter content (hashtag tweets surrounding DNC and Podesta emails), yet suppressed nothing negative about candidate Donald Trump…
Sounds like COLLUSION: secret or illegal cooperation or conspiracy, especially in order to cheat or deceive others.
In order for ‘COLLUSION’ charge to stand, you have to show evidence of Google, Facebook, and Twitter Co. actively colluded with Hillary Clinton Camp to suppress anti-Hillary and promote anti-Trump messages.
However, I think in this case, these tech giants simply censored viewpoints on their own.
At most, you can say they are not for free expression.
/Just my not-legal opinion.
