It’s maybe even more straightforward than that - anything that would be effective in preventing the government from collecting personal data through them would also be quite effective at preventing them from collecting that personal data in the first place, and then where would their profits go, eh? (Never mind that network television did quite well on advertising revenues for decades with considerably less information about their viewers…)
They aren’t doing anything significant because the unregulated status quo benefits them, pure and simple. (And that includes the lack of regulation on executive compensation, offshoring, etc., etc… Kick too much about one part and the whole Ponzi scheme falls apart.)
