It feels really odd seeing Engels' quotes used like this.
The focus of Engels' criticism when he made these statements was on *capitalist production relations*, where capitalists control the means of production and obtain profits by exploiting the surplus labor time of workers. This is precisely what DeepSeek and open-source initiatives are challenging. They are turning the means of production from the private property of capitalists into public property.
I hope you did not intentionally misquote this passage.
