I think it's rather disingenuous to complain about vague and un-named "internal and external problems socialism/communism has to contend with in the real world" in a thread about explicitly enumerated problems that capitalism has directly led to. The internet didn't become capitalist because socialism is inherently bad. The internet became capitalist be we live in a society run by capitalists and they realized they could exploit it.
