They are absolutely 100% complicit, and not just by chance, they are knowingly complicit. They take contracts from governments to censor and oppress their people. Just like IBM helped catalogue Jews in Germany and Standard Oil fueled the Nazi war machine, these companies take money to control information flows within dictatorships, hide atrocities and even provide information technology to help then further their aims in more concrete ways like biometric tracking and hacking tools.
And, btw, just to make this also explicit: if someone works for one of these companies--and aren't doing it in some way by force, or aren't working from the inside to actively sabotage the company's goals--they are also complicit.
