Let's say you're really determined to have freedom, so you buy a fancy new RISC-V single board computer. Fully open source architecture, bleeding edge stuff. You'll learn quickly the GPU relies on a closed source kernel that the OEM refuses to provide updates for after as little as a year or two, effectively acting as hardware DRM, when your device was supposed to be as free as it gets.
There are many roadblocks in the way of being a free software/open source fanboy.
Further, hyper-concentration of wealth is not something “made possible” by the internet. These problems existed before it and will continue existing. Because, if they are any problem at all, they are a social one.
In fact. 2 of the 3 were literally non-existant before the internet was created, so the internet is obviously not causing their dissolution.
Let me spell it out further: no matter how much people moan about it, Google does not have a monopoly on search in the way that the word "monopoly" is being used. There are several alternative (hello Kagi) and people are free and able to switch in less 30 seconds, they just don't want to and just don't care.
It should be pretty obvious that, even if the internet did not create concentration of wealth, it has certainly enabled it to a far greater extent than was possible before, which was the point. It would be petty semantics to argue over whether this means that it enabled "hyper"-concentration.
The history of Android is a story about the exploitation of 'open-source', not the incorporation of the benefits of software freedom into society.
Do you think that those projects wouldn't have existed with proprietary software?
With proprietary OS, all this hardware would be trashed. It would go in waste dumps or poor countries to be dismantled at high health and environment expense. And I would buy new hardware requiring more nature destruction with mining of rare materials. Finally this additional investment would decrease my financial capacity to do other things.
So to make a long story short, the many (millions?) people preserving their hardware investment with open source software are saving environment, health and money to a large extend.
And last but not least, they weaken software company monopolies, which can only be good for society as well.
