Rules:

Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

Us gear has kill switches in it.

Not only that, for decades now it's been rumoured the us has secret code on most all computers, a kill switch, blue screen of death.

I bet corporations have their own.

As far as regular CPUs go, it's not a rumour. Any AMD or Intel CPU made in the last 15 years can be remotely disabled via the network, even if the device is turned off (but connected to power).

Do you know how that manifests? Like if they killswitched it remotely, how would it stop working do we know?

I don't know how it behaves on ARM (so Apple's SOCs or your phone) but on Intel or AMD there are two manifestations:

They can intercept data and manipulate memory, and that's pretty much transparent, you wouldn't know unless you were a very advanced user running specific tests.

Or they can literally just brick the chip. It blows a few electronic fuses and corrupts it's own firmware, you press the button to turn on the device and it doesn't respond and will never respond again. Those fuses are permanent, once bricked its gone.
