I think there's room for both visions. Big Tech is generating more toxic sludge than ever, and yeah sure this is because they're greedy, but more precisely the root cause is how they lobbied Washington and our elected officials agreed to all kinds of pro-corporate, anti-human legislation. Like destroying our right to repair, like criminalizing "circumvention" measures in devices we own, like insane life-destroying penalties for copyright infringement, like looking the other way when Big Tech broke anti-trust laws, etc.
The Big Tech slop can only be fixed in one way, and actually it's really predictable and will work - we need to fix the laws so that they put the rights and flourishing of human beings first, not the rights and flourishing of Big Tech. We need to fix enforcement because there are so many times that these companies just break the law and they get convicted but they get off with a slap on the wrist. We need to legislate a dismantling of barriers to new entrants in the sectors they dominate. Competition for the consumer dollar is the only thing that can force them to be more honest. They need to see that their customers are leaving for something better, otherwise they'll never improve.
But our elected officials have crafted laws and an enforcement system which make 'something better' impossible (or at least highly uneconomical).
Parallel to this if open source projects can develop software which is easier for the user to change via a PR, they totally should. We can and should have the best of both worlds. We should have the big companies producing better "boxed" software. Plus we should have more flexibility to build, tweak and run whatever we want.
And then they will take away your right to boot whatever you want. For national security reasons and the children, of course.
Very good points, I agree and would add : "Interoperability" is the key to bring back competition and open the ecosystem again.
