I don't know how contrived the mechanisms have to be before people just accept that these ideological forces do not need *specific* mechanisms to exist. Tech firms did not produce liberalism and capitalism, as they did not exist when these ways of organizing emerged. Everything you described here are consequences of this system and the means by which it reproduces itself, they are not the system itself. Yeah, they organize, they do so because they have a common interest which is capital, and the imperatives of profit and infinite growth historically manifest consistently in formal and informal mechanisms of control like this. Class warfare doesn't apply here any better than it does to the informal consequences of neoliberal individualism which is both intentionally reinforced in media and culturally through its subscription by middle-class property owners. It may look coordinated, but that term distorts how these systems of power function and reproduce by creating the narrative that there is a select group of people responsible for this outcome, even while individual actions are taken to realise it.
