You fail to understand that in our modern reality, our data is our identity. Like computers, we too have vulnerabilities that can be exploited. Imagine how well a hacker could exploit software if he had access to the source code?
You fail to understand that Big Corporations DO care about our data. They harvest it precisely to manipulate our behavior for their benefit, at our expense. ("Digital Minimalism" by Cal Newport)
You fail to understand the many Big Corporations are essentially quasi-governmental organizations; they work in tandem with government to carry out agendas that are mutually beneficial to the government and the corporation, at our expense. Ask Edward Snowden.
You fail to understand that people are not paranoid. Many people simply understand that big corps may CURRENTLY take what is primarily a commercial interest, but as the political climate continues to shift, that primarily commercial purpose can pivot overnight to using your data to suppress dissent, influential voices, target members of whatever group they deem the "opposition".
You fail to understand how our lives are altered by Big corps Having access to our data. We are in an unfair fight; we are up against Big Corps that invest millions and millions into R&D to find the most effective ways to manipulate us to promote consumerism, for their profit.
> I think people are paranoid.
I think you're too trusting and need to think deeper about this topic.
