I can only hope that nothing ever happens to where I’d have to use Windows again. (been using only linux for over 10 years and the latest Windows I ever used was win 7 at work).
If that happened, the shock of all the last 10-15 years’ accumulation of enshittification hitting me at once might give me a stroke. The boiling frogs of today have gotten used to their OS serving them ads and spying on them by now, but I wouldn’t be able to deal with it.
You can buy a prepay phone at Walmart or similar, then just buy cards to add airtime. You don’t have to register your name anywhere. I had one like that for years.
