Open source is dead. That’s not a statement we ever thought we’d make. @calcom was built on open source. It shaped our product, our community, and our growth. But the world has changed faster than our principles could keep up. AI has fundamentally altered the security landscape. What once required time, expertise, and intent can now be automated at scale. Code is no longer just read. It is scanned, mapped, and exploited. Near zero cost. In that world, transparency becomes exposure. Especially at scale. After a lot of deliberation, we’ve made the decision to close the core @calcom codebase. This is not a rejection of what open source gave us. It’s a response to what risks AI is making possible. We’re still supporting builders, releasing the core code under a new MIT-licensed open source project called cal. diy for hobbyists and tinkerers, but our priority now is simple: Protecting our customers and community at all costs. This may not be the most popular call. But we believe many companies will come to the same conclusion. My full explanation below ↓

C) Want to explain to the community why Kucoin allowed a threat actor to launder $9.5M+ tied to a fake Ledger app via 150+ Kucoin deposit addresses over the past week? A few days before that another threat actor laundered $3.5M+ from the Bitcoin Depot incident via 25+ Kucoin deposit addresses. You’ve enabled instant exchanges abusing KYC and entities like AudiA6, a centralized mixer for illicit actors to operate freely. Kucoin deserves to have regulators come after its business once again.






🚨 LATEST: Cypherpunk Jameson Lopp and co-authors propose BIP-361 to freeze quantum-vulnerable Bitcoin, including Satoshi's $74B stash, before quantum computers can steal them.
