Socialism is not when the government does stuff, so those institutions are not examples of socialism. Anti-capitalists are arguing for the complete abolition of exploitative capitalist property relations that violate workers' human rights.
This is a false dilemma. There are other alternatives to capitalism besides communism. It is entirely possible to have a non-capitalist non-communist system (e.g. an economy where every firm is democratically-controlled by the people that work in it)
