Take Twitter's decision right before the 2020 presidential election to briefly block users from sharing a New York Post story alleging shady business dealings by then-candidate Joe Biden's son, Hunter, in Ukraine.
The article was based on files from Hunter Biden's laptop, which the Post said it got from Trump's private attorney, Rudy Giuliani, and former Trump adviser Steve Bannon. At the time, it was unclear whether that material was authentic. After being burned by the Russian hack and leak of Democratic National Committee emails in 2016, tech companies were on edge over the possibility of a repeat — and so Twitter decided to restrict the Post story.
Citing its rules against sharing hacked material containing private information, the company showed a warning to anyone who tried to post a link to the article saying it was "potentially harmful." It also suspended the New York Post's own Twitter account until it deleted its tweets about the story. (Facebook was alarmed by the article, too, but didn't go as far as Twitter. It allowed the link to be posted, but limited distribution of those posts while its outside fact-checkers reviewed the claims.)
Twitter's aggressive stance immediately created a huge backlash across the political spectrum. The company was slammed for taking a heavy-handed approach to a story that, while controversial, was being reported by a major news outlet, and for offering little justification for its decision. Within days Twitter reversed the block and changed its policies on hacked materials. Soon after, then-CEO Jack Dorsey said the company had made a mistake.
That's all been publicly known and widely reported on over the past two years. The material shared by Musk paints a more vivid picture of the scramble inside Twitter to figure out what to do — but does not fundamentally alter that picture.
And it does not show any evidence that there was government involvement in the move to block the New York Post story, despite assertions by Musk and others.
