Mark Cuban Slams Bluesky for Lack of Political Diversity

Billionaire entrepreneur Mark Cuban is voicing frustration with Bluesky, a social media platform that gained popularity as an alternative to Elon Musk’s X. In a series of posts, Cuban claimed that Bluesky has become "ruder and more hateful," citing a growing lack of tolerance for political diversity.

"The lack of diversity of thought here is really hurting usage," Cuban wrote. He lamented the shift away from nuanced debates, adding, “There used to be great give and take discussions on politics and news. Not so much anymore.”

Cuban, who joined Bluesky in late 2024, was once among its most vocal supporters. His early post, “Hello Less Hateful World,” reflected his initial optimism. But after posting nearly 2,000 times, his tone has shifted. He now accuses the platform’s predominantly left-leaning user base of creating a hostile environment where even minor disagreements are met with aggressive backlash.

Cuban pointed to instances where users labeled him a “fascist” for expressing mild dissent or offering grey-area opinions, saying, “Engagement went from great convos to agree with me or you are a nazi fascist.”

His criticism triggered a wave of harsh replies. Some users told him to leave, mocked his billionaire status, and accused him of promoting corporate interests. Cuban reposted one comment that read, “We want you to stop pushing AI and big business here and just Go Away.”

Cuban warned that if the current trend continues, users would migrate back to Elon Musk’s X, formerly Twitter. “We are forcing posts to X,” he wrote, implying that Bluesky’s stifling environment was pushing users away.

Bluesky had seen massive growth following Musk’s endorsement of Donald Trump’s 2024 reelection bid, which caused millions to exit X. According to Pew Research Center, Bluesky’s user base tripled between November 2024 and May 2025, with many prominent influencers skewing left politically.

In a June 4 podcast with Vox’s Peter Kafka, Bluesky CEO Jay Graber acknowledged the platform’s politically motivated growth. “It’s people looking for something, and people looking to get away from something,” she said.

While Bluesky initially promised a decentralized, welcoming alternative, Cuban now believes that the platform’s culture is discouraging meaningful discourse.

Once a Bluesky enthusiast, Cuban now sees the platform as an ideological silo that alienates moderate and opposing views. His public departure from the platform’s tone underscores growing concerns about online polarization—even on platforms built to escape it.
