> I think he's saying that his "professional journey building OSS" is over. ie his day job needs to generate income.

I agree that he’s saying this. But FTA:

> Open source is great, but it's not sustainable. We self-sabotaged ourselves over decades, and now we're at a point where it's hard to turn back. Publishing source code for the greater good is a noble cause, but to be honest, I think that over the years, using "open source" has become an excuse to avoid paying for software.

I interpreted this as something beyond just his personal position, and seemed like a broader indictment of the OSS model.
