Just because it's free? Let's talk again when all open source projects are funded and controlled by the state with zero competition between them and no consumer choice. Only one Linux distro, only one database, only one web framework, etc. And it's decided top-down from the state what to work on. I doubt though that these projects would have started in the first place in a communist setting.
"The" state, with no competition, like there's only one state?
Belgium isn't big enough to realistically have its own linux, but France and Germany are.
Yours and others knee jerk reaction proves my point you are conflating autocracy with communism/socialism.
This is as usual confused. People keep discussing communism as if they were (via analogy) talking about capitalism being about men in suites with fake smiles, green paper, bank vaults, and powerpoint presentations. Every time people have to respond with paragraphs upon paragraphs just unrolling all that nonsense.
Try to update your knowledge on the subject instead of talking like an alien in Trafalgar Square.
There is no reason such a state would have to set things up this way.
As an example: you probably know that germany has socialized healthcare. It is, however, not implemented as a single-payer model. Instead there are tons of different insurances competing with each other, while having a highly regulated floor of what they MUST offer.
Is the model perfect? Hell no, it has tons of issues - though overall it's pretty solid. My point is just that social policies and "no internal competition ever" does absolutely not have to go hand in hand. There is a massive middle ground.
See: social democracy as a concept and in its current implementation.
