But Cuban has changed his tune. In a series of posts this week, Cuban argued Bluesky has become too much of an echo chamber, and is sending more users back to X.
“Engagement went from great convos on many topics, to agree with me or you are a nazi fascist,” Cuban wrote. “We are forcing posts to X.”
The former Shark Tank star and Dallas Mavericks owner also said he thinks Bluesky users have “grown ruder and more hateful.”
Bluesky did not respond to Fortune’s request for comment.
“The lack of diversity of thought here is really hurting usage,” Cuban wrote in a separate Bluesky update including the Washington Post article. “The moderation and block tools on here are so advanced, if you see someone you don’t want to see on here, just block them. Don’t attack them.”
“There used to be great give and take discussions on politics and news. Not so much any more,” Cuban added. “Doesn’t have to be this way.”
