That's interesting. I have also been waiting for the resurgence and takeover of free software over non-free software for many years, so that we can inspect, modify and run the software freely without restrictions on our computers.

How did the point of "open-source" get hijacked so quickly by the tech bros who have also helped the surveillance capitalists agenda and exploit more of these free-software developers to the point where they end up working for the likes of surveillance capitalist big tech companies using open-source projects (and privately modifying it) for free to accelerate and speed up pushing their closed-source spyware?

I think maybe both of these concepts that many technologists have envisioned have become quite frankly hopelessly utopian and instead has helped pave another road to a dystopian hell.

I don't think that the idea of either free software or the semantic web were hopeless or that they lead to the dystopian hell. Open source was created due to a disagreement with the idea of software freedom. It turned out to be exactly what free software wasn't - a tool for exploitation. Similarly, the semantic web was easy to implement - except that the big tech saw it as a hindrance to profit. That lead to the blockchain web hijacking the web3 designation from it. That said, both ideas are still viable and still alive on a small scale.
