I have some quotes to share, though about the government side of things

"The digital age has created the semblance of social connection, while empowering autocrats to better surveil, control, and disrupt perceived political opponents. China, Iran, Russia, and Saudi Arabia have used digital tools to silence opponents, spread propaganda and disinformation, and sow polarization and division among their rivals. So, too, have regimes in smaller countries, like Togo and Bahrain, relied on digital surveillance to curtail civil society. Recent trends among mass movements also show some cause for concern." (Erica Chenoweth - Civil Resistance: What Everyone Needs to Know)

And 3 from "No Place To Hide":

"Initially, it is always the country’s dissidents and marginalized who bear the brunt of the surveillance, leading those who support the government or are merely apathetic to mistakenly believe they are immune. And history shows that the mere existence of a mass surveillance apparatus, regardless of how it is used, is in itself sufficient to stifle dissent. A citizenry that is aware of always being watched quickly becomes a compliant and fearful one."

"All of the evidence highlights the implicit bargain that is offered to citizens: pose no challenge and you have nothing to worry about. Mind your own business, and support or at least tolerate what we do, and you’ll be fine. Put differently, you must refrain from provoking the authority that wields surveillance powers if you wish to be deemed free of wrongdoing. This is a deal that invites passivity, obedience, and conformity. The safest course, the way to ensure being “left alone,” is to remain quiet, unthreatening, and compliant."

"Mass surveillance is a universal temptation for any unscrupulous power. And in every instance, the motive is the same: suppressing dissent and mandating compliance. Surveillance thus unites governments of otherwise remarkably divergent political creeds. At the turn of the twentieth century, the British and French empires both created specialized monitoring departments to deal with the threat of anticolonialist movements. After World War II, the East German Ministry of State Security, popularly known as the Stasi, became synonymous with government intrusion into personal lives. And more recently, as popular protests during the Arab Spring challenged dictators’ grasp on power, the regimes in Syria, Egypt, and Libya all sought to spy on the Internet use of domestic dissenters. Investigations by Bloomberg News and the Wall Street Journal have shown that as these dictatorships were overwhelmed by protestors, they literally went shopping for surveillance tools from Western technology companies. Syria’s Assad regime flew in employees from the Italian surveillance company Area SpA, who were told that the Syrians “urgently needed to track people.” In Egypt, Mubarak’s secret police bought tools to penetrate Skype encryption and eavesdrop on activists’ calls. And in Libya, the Journal reported, journalists and rebels who entered a government monitoring center in 2011 found “a wall of black refrigerator-size devices” from the French surveillance company Amesys. The equipment “inspected the Internet traffic” of Libya’s main Internet service provider, “opening emails, divining passwords, snooping on online chats and mapping connections among various suspects.” The ability to eavesdrop on people’s communications vests immense power in those who do it. And unless such power is held in check by rigorous oversight and accountability, it is almost certain to be abused."
