Zuckerberg didn't really say anything about altruism. The point he was making is an explicit "I believe open models are best for our business"

He was clear in that one of their motivations is avoiding vendor lockin. He doesn't want Meta to be under the control of their competitors or other AI providers.

He also recognizes the value brought to his company by open sourcing products. Just look at React, PyTorch, and GraphQL. All industry standards, and all brought tremendous value to Facebook.
