Alternativelly, multiple subgroups within the power elites can support the same things for different reasons.

It’s perfectly logical that, for example, intrusive tracking under the excuse of Age Checks “to protect the children” is supported by the Pedophiles because it helps them detected early and suppress attempts to change the very system which gives them immunity for their crimes, non-Pedophile people in positions of power support it for very similar reasons only they just want to stay in power because they like power or because of the money and priviledges they get from their position in that system and big companies selling media to users support it because it lets them more strongly bind copies of that media to specific users hence people can’t share it (for example, two sibblings in the same house using the same device can’t share a single copy of a game) so those companies sell more copies hence make more money.

Reducing most people’s choices can serve different stakeholders who have different desires and often do so for different reasons.

Trying to come up with a Theory of Everything for it is excessivelly reductionist and even simplistic - just because it’s easier to get one’s mind around a “they’re all the same” explanation than around something like what I’m putting forward, doesn’t mean the former is the right explanation.
