Remember when social media was supposed to be a marketplace of ideas? That illusion shattered the moment Elon Musk took over Twitter and committed to restoring free speech. The left didn’t respond with debate or dialogue—they ran. First to Mastodon, then to Threads, and eventually to Bluesky. Why? Because today’s progressive movement can’t stand to share digital space with anyone who doesn’t parrot their every belief. They don’t want a conversation—they want a controlled environment, a curated bubble where dissent is treated like violence and differing opinions are branded as hate speech. And now, to no one’s surprise, Bluesky has become exactly that: a digital echo chamber built for ideological purity and allergic to any real diversity of thought.
Mark Cuban may be late to the party, but he’s finally seeing the rot for what it is.
In a series of posts this week, Cuban lamented the sorry state of Bluesky, a platform he once joined with a sunny “Hello Less Hateful World” message. That optimism didn’t last. “Engagement went from great convos on many topics, to agree with me or you are a nazi fascist,” he wrote. He now admits Bluesky has devolved into a one-note echo chamber, where even the slightest deviation from far-left orthodoxy gets you branded as a heretic.
“Even if you agree with 95% of what a person is saying… they will call you a fascist,” he observed.
I’m surprised it took him so long to figure it out. This week, a graphic has gone viral on X showing how there is “more diversity of thought on the political Right than on the political Left.” My first reaction to this was, “Well, duh.”

Let’s be honest—this isn’t some shocking revelation. Anyone paying attention has seen it coming for decades. But the left still loves to pretend they’re the champions of open-mindedness. Now, Mark Cuban just got a rude awakening about the rigid, authoritarian mindset that dominates the woke left. Cuban’s realization of the oppressive groupthink of Bluesky is a perfect example of how true the above graphic is.
“Even if you agree with 95% of what a person is saying on a topic, if there is one point that you might call out as being more of a gray area, they will call you a fascist etc.,” Cuban observed.
Well, yeah, haven’t you been paying attention?
It’s good that Cuban is finally saying what many on the left won’t: The dogmatic purity tests, the mob tactics, the scorched-earth replies to anyone remotely heterodox—it’s all pushing some of the more reasonable people back to X. Which doesn’t surprise me at all.
This was the natural endgame for a site that grew by vacuuming up the most triggered Twitter (now X) users fleeing Musk’s digital town square. Bluesky’s user base experienced a decent surge—from 10 million to over 30 million between November 2024 and May 2025—but, according to reports, their active user base has been steadily declining.
“The lack of diversity of thought here is really hurting usage,” Cuban observed. “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.”
In the end, Mark Cuban’s gripes about Bluesky aren’t just about a broken social media platform—they’re a snapshot of what the Democratic Party has become. A movement once cloaked in the language of tolerance now devours its own at the first hint of dissent. The rigid groupthink, the moral grandstanding, the instant vilification of anyone who dares color outside the lines—it’s all there on Bluesky, playing out in real time. Cuban thought he was entering a haven for reasoned discourse, only to find himself surrounded by ideological puritans eager to label even minor disagreement as heresy. Welcome to the modern left, Mark. It’s not just your app that’s toxic—it’s the entire party.
