He didn't mention Musk by name. He made it clear in a post on Tuesday that the company he once led had serious problems.
He said he was adding his voice to the discussion about Musk's claims that prior management was biased against conservatives.
He said at the beginning of his post that he believes in three principles. Moderation is best implemented by algorithmic choice, and the author is the only one who can remove content.
The current version of the micro-messaging service does not meet any of the principles laid out in the letter.
Many of the moderation policies have been rolled back by Musk. Donald Trump was kicked off the site permanently after the January attack on the U.S. Capitol.
No one leveled any criticism at Musk. He said he abandoned his efforts to push the company in the right direction after the company was taken over by an activist firm.
He wrote that this was his fault. When an activist entered our stock in 2020, I gave up trying to get them.
There was no ill intent or hidden agendas, and everyone acted according to the best information we had at the time, according to the statement from the man.
If the company focused more on tools for the people using the service rather than tools for us, it would be a better situation today.
In general, social messaging platforms shouldn't take down content or suspend accounts because doing so complicates important context, learning and enforcement of illegal activity
He believes that a free and open protocol for social media is the only way to follow his principles.
There are companies who own both the protocol and discovery of content. One person is in charge of what is available or not.
Bluesky is one of the projects that could potentially live up to his view of what constitutes a free and open social media protocol. He said he would be giving $1 million to the project.
It's a public square and should not be restricted by the government.
