This all seems like a major publicity stunt. We all know that Twitter is filtering users. The question is why they are filtered. There's a clear bias to specifically show right wingers being banned but other independent sources say it is roughly even. I don't want to really see political leanings so much as I want to see the content that caused them to be flagged in the first place. If someone promotes Nazism or some other universally hated sentiment I don't care which party they belong to.
I want to know WHY these people were flagged.
Without that being said I can't read these (and the previous posts) as any more than propaganda. It has a right wing bias and that feeds into a prior narrative but we all know that social media is amazing at causing selection bias. If they really want to show that Twitter's prior policies favored the left wing then they need to show more data and fewer direct examples. There's been this narrative that most employees at Twitter are left wing therefore filters target right wingers but that is naive unless we assume all Twitter employees' voices are equal and equally contribute to the creation of these filters.
This isn't so much whistleblowing as it is propaganda. Musk wants to drive eyeballs and the master of hype is doing what he does best. Lord around a nothing burger and promises the moon. He's just using that right wing prior that many have and exploiting that with selection bias without actually demonstrating that there is a bias.
