IIRC, Cuba also embraced FOSS to an extent.

I legit put a defense of it on a communist youth pamphlet we targeted toward the Compsci center. All countries that want any tech sovereignty should build FOSS stat

It’s all nothing without putting it to practice tbh. I think practicing actual Marxism-Leninism is what’s lacking. Plenty of academic works exists if you know where to find them

Not that I’m against making stuff more accessible, but I find that works best when allied to actual parties and such. In Brazil for instance plenty of my comrades in the Brazilian Communist Party (PCB) are translating works from their source Russian texts and publishing them online and to books. Helps fundraise too.
