I've seen rumblings that day may be very soon, too. Once devices in the home have embedded prepaid 5G out with your control, all sorts of home networking/firewall challenges are going to arise. We are entering a world in which it will cost very, very little to embed 5G into almost anything with say 1GB of prepaid eSim data for analytics collection, regardless of whether device resides on your LAN or not.
There’s only a fractional amount of people using smart TVs without WiFi. I’m very dubious it’s worth the cost to imbed GSM cards in each TV to reach the fraction that doesn’t allow the TV on WiFi.
I've long wondered about what wifi/cellular looks like on an infinite timescale... it does strike me as unlikely too we will maintain two separate wireless standards forever for IP data. I think embedded cellular or equivelent global wireless access will one day just be as taken for granted as embedded wifi in a lot of devices. Technologies like eSims are all steps in this direction.
I've seen others in this thread argue embedded cellular isnt worth the cost, but this misses the critical point - if it costs almost nothing (we are close to this point already) and is already built into every off the shelf SoC, of course manufacturers will use it. We are talking pennies per unit at scale here in future.
The auto industry has already done this - Ford for example have embedded cellular analytics you can't turn off (or at least its non-obvious to me as an owner) on every single new Ford and has done so for several years now, and you don't pay a penny as the end user, even on their most basic entry level cars.
It wouldn't last five minutes on my car without being disabled. Easy to do, use a portable spectrum analyzer, find the source of the RF and then nuke the antenna.
Same goes for any other appliance that radiates RF signals (IoT, etc.).
You don't stop internet access or do anything to alter the electronics. By blocking the car from transmitting and receiving cell signals it's effectively the same as the car being out of cell range.
If cell access is essential, what happens in a place without cell access, much of Alaska perhaps?
I hate to think of all the lawsuits resulting from drivers who drive into locations where cells are out of range and get stranded.
Similarly, what happens when the cell phone system breaks down? And does that mean I can't buy a car if I live in an area with intermittent, weak or no cell or internet service? Hate to think what the manufacturer's sales department would think of that.
On the matter of reverse engineering, it seems to me we're just on the cusp of that. Hackers as still getting organized and aftermarket manufacturers have still to tool up for complete computer replacement kits. Reckon we're only at the very beginning of whole new industry.
Oh, I nearly forgot, the Right to Repair movement has only just begun to get organized. If manufacturers try to stop us altering something we've paid goid money for then they'll be in for a long political fight.
As I said above, just nuke the antennas (a box cutter through the antenna leads is usually enough. If you're really paranoid, short the lead out at or near the equipment end (as near as to the feed IC as is possible).
I do this on old smartphones that I have no intention of ever using as a phone again (say for testing APS etc.). It's dead easy, a razor blade through the circuit board tracks that connect to the antenna(s) and it's all over—no phone, with or without SIM (i.e.: no emergency service) and no WiFi or Bluetooth.
