The powerful have always been able to oppress the weak, and abandoning all technology to go anarcho-primitivist leaves the powerful better-resourced than ever, and leaves you scraping out a marginal living. Moreover, as technology continues to advance, the need for mindless conformity is further eroded. Mass production was pretty mind-numbing, but now we have robots to do the most mindless tasks, and we are getting more of them.
The solution to control and repression, now as ever, is to structure society so that ambition can counteract ambition, to enshrine the rights of the people in law, to jealously guard those rights, and to inculcate the next generation in their value. The US Constitution does an absolutely world-class phenomenal smashing good job of the first two, such that even as society has been doing a mediocre job at guarding them and teaching their value, we're still getting by, and improving.
If you'd like to fight control, in the abstract, don't bomb people: preserve the system that protects us through civic engagement, and work to build a culture that celebrates the robust defense of rights like free speech (including, critically, of unpopular people you don't like who are targeted by the mob or by the powerful) and other civil rights (criminal justice issues in particular).
