Sounds like the teaser for “CommieNet: The Nerds Strike Back”, but on a serious note, I think you are right.
In some sense, digital resources are non-scarce resources, they can be copied and multiplied. There is no capitalistic pressure innate to information, not in the way we consider other resources to be scarce.
But such a digital utopia still would have costs for hosting the content and it would need to stay afloat in the profit-oriented world with finite resources and hard costs for running servers. So it would have to be donation based, or subscription based. Ironically, inside it would have to be strict about prohibiting anything that is effectively monetizing anything that happens inside.
And someone would get the money earned from these subscriptions or fees and this would necessarily end up being some non-profit organization which would have to be somehow community driven, and would decide what is accepted in the space it has to take care of.
But this sounds like a kind of internal governance, like a whole state, a body of rules, that exists within the community of everyone participating in that special network. This council would have responsibility to prevent corruption on the network and at the same time prevent it’s own corruption.
I could go on, but I guess it’s pretty clear that creating a uncorruptible social space is exactly the same problem as creating an uncorruptible truly democratic society. If you figure this out for an internet platform, you have figured it out for the real world.
So I guess it’s not gonna happen ever. It goes always like this - something nice grows, at some point it starts to rot, implodes, from the ashes something new can emerge, rinse and repeat. Just humans being humans.
In the old days, a few motivated nerds could write a browser. Now all you can realistically do is take a browser engine and build some user interface around it. That what most “alternative browsers” do - tweaking or repackaging.
These days, a browser is like it’s own operating system with sandboxing, various Interfaces to periphery devices, hardware acceleration for GPU and all the bells and whistles taken for granted now.
I’d say that imagining it to be on a scale similar to working on the Linux Kernel is more right than wrong.
So we definitely very much want Firefox to survive, or it will be much worse than the Linux/Mac/Windows trilemma. Microsoft Edge is chromium under the hood too. Any many desktop “apps”.
