There's a big difference between a giant corporation (that wants you to continue using its products) seeing every site you've visited, and your fucking employer, source of not being homeless and starving to death.
No not really. I mean you could never connect to the internet I guess. But that's the best mitigation there is as long as your using windows. Or run it in a VM?
So you can understand how this works, each device in your computer has a uid or hid, a unique id, or hardware id. This remains consisten as long as you have the hardware. Things that have this are like hard drives pcie cards, etc.
There's also just the fundamental unique ways your PC is built. Of all windows users how many have an Nvidia card? 90% of those 90% how many have the same drive configuration. 5% of those how many are running Intel CPU. Etc etc...
The only way :) Once I stopped using all proprietary software, I also quit social media (this account is the first one after such a long time) and I've never felt happier. Linux and privacy for the win!
