Cars, your TV, your phone, everything is fucking spying on you. At this moment I am more interested in how I generate a tsunami of more data about me to the powers that be to drown them in a deluge of irrelevant bits.

Yes, and that's very sad. However the solutions are pretty obvious:

Car -> unplug the cellular modem (more or less easy)

TV -> used as dumb monitor with a Linux HTPC

Phone -> GrapheneOS

PC -> Linux

Social media -> /dev/null

Email/DNS/cloud -> my own

The real issue is that most people are not aware of these issues and may even (unintentionally) compromise your own privacy by posting information or pictures of you to Facebook or other similar places.
