Scouting report
Founded Facebook in a Harvard dorm in 2004 and still runs the company two decades and about three billion users later, through Cambridge Analytica, the Instagram and WhatsApp deals, and the pivot to Meta. The open source record is enormous and largely separate from the reputational one: React, PyTorch, GraphQL, RocksDB, the Open Compute Project, and the Llama open-weight models.
Curator’s note
The most-criticised CEO in tech also runs its largest open source operation.
