When Edward Snowden was working for NSA he decided to stand against status quo and leak information about global surveillance programs, many which are run by the NSA in cooperation with telecommunication companies and European governments. This is the tip of the iceberg in regards to surveillance measure of governments and Big tech today. Edward Snowden was forced to leave US to avoid imprisonment for sharing this information to people who are the targets of this surveillance.
Julian Assange, currently imprisoned in UK, is one of the founders of Wikileaks. He is charged with espionage by US for sharing the truth about US war crimes in Iraq and Afghanistan. In regard to surveillance, Wikileaks published extensive materials on CIA projects to intercept SSH credentials, target Linux, Windows and MAC systems, utilize webcams and suspend video recordings and also published research about Amazon's collaboration with the US Department of defense and CIA, and surveillance contractors in Russia to name a few.
Google holds over 70% of the browser market and through IP addresses tracks what we do on internet. Big tech collaborate with government by handing over information on demand. Even when we are not online, society is digitalized which faciliated enforcing control measures. When we move in society cameras are watching us or the electronic cards we might use for transportation or payment map out our lives.
To develop open source software which aims to bring privacy solutions to users is becoming criminalized. When Tornado cash developer Alex pertsev was arrested in Amsterdam, US government publicly tagged all Tornado cash users. The current push to regulate crypto including imposing CBDC (Central Bank Digital Currency) is a way for nation-states to co-opt crypto, control people and money flow.
If we want to opt out of the surveillance system, we need to build privacy tools, share knowledge and resources on what is already existing.
