In what sense is adding a link to an article that contradicts and, indeed, refutes something you say "censorship"?
Moreover, having enjoyed the freedom to abuse Twitter as his personal soapbox for over a decade, it's more than a little precious of Turmp to get so hurt when finally they call him out on just a little of his BS and he decides to abuse Presidential powers in response.
What is, perhaps, the most disappointing about this is that Twitter decided to take no action on a far more egregious tweet of Trump's, one where he suggested without evidence that Joe Scarborough was involved in the death of Lori Klausutis. That truly was disgusting, especially as Klausutis's widower asked Twitter specifically to take action, and especially as Trump ignored that same message and refused to withdraw his libellous and disgusting comments.
