No one is. These Twitter Files are just building on a right wing prior of them being shadow banned. But they have yet to demonstrate that right wingers are specifically targeted. They don't show why these accounts got flagged (the crux of the issue and none of this means anything without demonstrating this knowledge) but just show prominent right wingers that did get flagged. We just get left with more questions. Do prominent left wingers also get flagged? Do prominent left wingers act in ways that would similarly be flagged? Is flagging biased? (I'm sure it is, but lets' measure it)
It is a common statistical manipulation through leading someone to causal conclusions via selection bias (sometimes called "malinformation"). While not directly said these tweets (and the previous ones) are targeted to make the reader believe that Twitter silences right wing voices. This may very well be true, but they have yet to provide strong evidence of this. Just samples. Problem is, we don't know anything about the distribution of samples so we have no means of determining if they are cherry-picked or not.
