None of the three people you named (two of whom I never heard of) got Trump elected. Trump got Trump elected.
I will not change my mind about this so it is not necessary to try and persuade me otherwise.
They are just a small sample of people who got Trump elected, there are scores of others who are also being deplatformed. You seem to underestimate their importance. Whilst Trump is busy being president, the MSM and leftist social media types are coming up with anti-Trump material and he has better things to do that spend time refuting everything, which is why he needs social media content creators to do this on his behalf, because collectively, they have a reach of 10s of millions, particularly younger people who will be voters long into the future. He scraped through at the last election because the establishment did not fully grasp the importance of social media, now they do and are working to ensure they are the only ones who set the narrative. Once Trump is gone, nobody else of his ilk will be able to use social media to reach an audience because they will be nipped in the bud long before their popularity becomes a threat. In the future you will NOT be able to win an election unless you and your supporters have the freedom to espouse your message on social media. This is a fact.
