In 2018, the Cambridge Analytica scandal revealed that Facebook data from over 87 million users had been harvested to influence elections in the United States and abroad (BBC). A year earlier, the Equifax breach exposed the sensitive financial data of 143 million Americans (FTC). And in 2013, Edward Snowden’s leaks uncovered vast surveillance networks where governments worked hand-in-hand with major technology providers (The Guardian). These events made one thing clear: Big Tech companies aren’t just shaping markets—they are influencing global politics, privacy, and personal freedoms.
From search queries and location tracking to app permissions and cloud storage, Big Tech thrives on data. Companies like Google, Apple, Facebook (Meta), Amazon, and Microsoft have built empires by monetizing user behavior. This includes:
Search history and browsing patterns (Google, Microsoft Bing)
Social interactions and preferences (Facebook, Instagram, WhatsApp)
Shopping behavior (Amazon, eBay)
Voice and facial recognition (Apple’s Siri, Google Assistant, Meta’s AI)
These insights aren’t limited to selling ads. They increasingly play a role in shaping policies, manipulating public opinion, and even strengthening governments’ surveillance abilities.

Big Tech companies are not neutral players. Their influence extends across borders:
Google and Russia – Reports have shown cooperation between Google and Russian authorities on selective censorship and data handling.
Apple in China – Apple has faced criticism for storing Chinese users’ iCloud data on servers in China, giving the government more access.
Meta in the Middle East – Social media platforms played a pivotal role in mobilizing protests during the Arab Spring, with governments later using the same platforms for surveillance and propaganda.
TikTok Investigations – Questions around TikTok’s ties to China highlight how platforms can become geopolitical tools, raising alarms in the U.S. and Europe.

By exploiting Facebook user data, Cambridge Analytica created psychological profiles to target voters with hyper-specific political ads. This sparked global outrage and highlighted how vulnerable democratic processes are to data misuse.
In one of the largest breaches in history, Equifax failed to protect sensitive data like Social Security numbers and credit card details. The fallout showed how personal data in the hands of corporations can create systemic risks when improperly secured.
Edward Snowden’s disclosures showed how the NSA worked closely with tech providers to collect metadata, monitor communications, and share intelligence internationally. This blurred the line between Big Tech’s corporate interests and governments’ security agendas.

Through app permissions – Many apps request access to contacts, microphones, and cameras unnecessarily.
By tracking movements – Location data is continuously logged through smartphones, even when GPS is turned off.
Via AI-driven profiling – Machine learning algorithms predict behavior and preferences, sometimes more accurately than we know ourselves.
By selling data to third parties – Advertisers, governments, and data brokers purchase user insights.
While you can’t completely escape the reach of Big Tech, you can reduce your exposure:
Use privacy-first tools – Switch to encrypted messaging apps like Signal or ProtonMail for email.
Review permissions – Limit unnecessary access on apps and devices.
Adopt VPNs – Encrypt your browsing traffic to shield it from both hackers and providers.
Secure devices physically – Tools like Faraday bags and secure sleeves block wireless signals and tracking attempts.
Consider DeGoogled phones – Phones that run on privacy-focused operating systems reduce the constant flow of data to Big Tech ecosystems.

Big Tech companies are more than service providers—they are gatekeepers of global data flows, with influence stretching from advertising boards to national security councils. Their role in surveillance, election manipulation, and international politics makes them as powerful as some nation-states.
For individuals, the challenge is clear: reclaim as much control as possible over personal data. At Freedom Technology and Services, we provide practical tools like Faraday bags, RFID-blocking wallets, and secure sleeves to help you take back your digital freedom in a world increasingly defined by Big Tech spying.
