See the aforism "Privatizing profits and socializing losses". I think the author is saying that the costs are being socialized by having taxes fund construction and maintenance while the owners are making it happen via the mechanism of crony capitalism.

Privatizing profits is not compatible with socialism though. Not even close.

It's sloppy language to call it "socialism" but it has socialistic properties. The worst of socialism mixed with the worst of capitalism presented under both terms so people from both sides will agree.

yes, this is clearly a case of communist-capitalism a la China and Russia; there's nothing socialist about it.
