Not since the beginning. They made it that way after beef with the IRS.

I wish they hadn't because they are thinking too commercial (extremely high paid CEO) for instance but they have a foundation to answer to which doesn't manage them like shareholders would (eg not rewarding the CEO for dropping marketshare!). This model is the worst of both worlds imo.

That's the same basic structure, on paper, as OpenAI, it didn't “switch to for-profit” in terms of taking the nonprofit entity and converting it to a for-profit.
