This does not mean that big tech companies are not capitalist in the sense that ordinary people use the word "capitalist", nor indeed in the sense that economists generally use the word "capitalist" either. No critic of capitalism intends for their critique not to apply to actual businesses as they must exist (even Valve). It may be an interesting fact that firms are not organized unconsciously according to a price mechanism, but it is not a surprising one nor of any particular salience here.
This "ordinary" definition of capitalism is vacuous because it views all mixed economies as "capitalist" economies. It's a fallacious definition that marginalizes economic "socialism" as an impossible bogeyman (i.e. zero private property). TINA and all that.
