Throw your phone and computer out. Get rid of your TV and cars unless it’s a 1980 or older. Totally off the grid so to speak.
Short of that there’s not much you can do.
Big tech is everywhere especially if you log into anything regardless of your operating system.
An overreaction. Computers like my G5 quad (or even the G3 in the closet) are only really handicapped as gaming platforms. And there are still good games to play on them if you don’t need the latest fare.
We can still, at least for now, turn off use of the cloud or location “services” too.
Cars which have electronic controls don’t even start to get things like GPS or OnStar till long after 1980.
TVs with these objectionable features weren’t the inexpensive TVs till fairly recently. Indeed, what’s ON TV NOW is far more of a concern than those TVs.
my car is from 2006. How is it ‘gaggle’ compromised?
