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.
HN is not a social media platform in the traditional sense. For one, it is completely anonymous, unless your "handle" is somehow linked to a real identity (by choice or otherwise). It's very, very different from posting every aspect of your life on a platform like Facebook.
