Did you know a recent Coldcard hack cost users over $100 million in bitcoin — and exposed a major misunderstanding about what “open source” really means? The popular hardware wallet lost more than 1,500 BTC, raising questions about Bitcoin software incentives. Coldcard’s firmware is often described as open source, but it’s released under MIT plus the Commons Clause. That clause removes the right to sell the software, and its own FAQ says: “Is this ‘Open Source’? No.” True open source requires free redistribution, source code access, and permission for derived works, including commercial use. Without commercial liberty, there’s less incentive for third parties to audit and test code — a tragedy of the commons. Auditable code isn’t the same as fully open code. $BTC #Bitcoin #OpenSource #SelfCustody
