I strongly suspect that any images of him are AI generated, and this is a psi-op.

Cars.

Most any vehicle made after 2006 will have one or more of these three issues:

1. Lack of repairability. Not just computerization, but auth to the point where changing your brake pads and rotors can make your vehicle refuse to move until those brakes and rotors are authorized over the Internet by the vehicle manufacturer. And the software to do so costs $1M to buy, needs a $6k/mo subscription, and can only be bought by authorized dealers, locking out independent repair shops.
2. Privacy. Almost all vehicles after 2006 and any before that with OnStar records everything the vehicle does and sends that up to the mothership to be repackaged and sold to data brokers. Then your insurance gets a copy and jacks up what you pay because you braked hard and sped slightly over the limit a few times. Modern cars will also record everything that happens inside and around the vehicle, to the point where when you buy the car you have to sign a waiver that states they have permission to record anyone doing anything inside the vehicle, up to and including having sex in the back seat.
3. DRM. When you buy a vehicle with all the bells and whistles, but many of those bells and whistles are shut down until you pay $$$/mo to have them turned back on. Sorry, but if the vehicle came with it, I will gleefully crack that software until I can use that feature. I paid for it when I bought the vehicle, so I have every right to use it without paying a cent extra.

It’s time people started to pack a dark hoodie and a battery powered angle grinder wherever they go.

These cameras need to be taken down the instant they appear.

You have a network for employee’s personal phones and devices, correct? That still leads to the Internet, correct?

I mean, the entire point of such a network is to keep outside devices off of internal networks that have sensitive data. And because the insides of large buildings can be absolutely sucky at receiving LTE/5G data connections, employees can and will do anything needed to ensure they still have connectivity on personal devices. So just connect the router/bridge to that network, and Teams will be appropriately sanitized and think you are still at home.

I have seen very tiny router/bridges, clear down to an Ethernet dongle with a +5v USB power feed. Quite unobtrusive.

If possible: grab a router and install OpenWRT onto it, and turn it into a wireless bridge. Use the router to connect to the office WiFi, and have a wired connection to your laptop. Turn off the laptop’s wifi for good measure.

Alternatively, if work provides hard lines, bring your own router and turn off WiFi to provide a protected hardline.

There are many ways to prevent the computer from realizing what network you are on.
