lol anyone that has experience with Amish in Ohio knows phones are everywhere.
Hell I saw an amish dude ripping down the street on a one wheel just a few months ago. Some use side by sides and tractors. They also have a battery distributor with their own name on the label and a website, Miller Tech.
It depends on the community but in my experience it's not much of an issue at all these days.
I've lived near a few Amish communities, and they're all a little different on what tech is present but it's safe to say they all have some.
Generally you'll see electricity and phone lines to a special building, they won't all have it but a few will. Lately they've ditched the landlines for cell phones, and they'll have their spouses put parental blocks on them.
The philosophy doesn't really change much, it's not about rejecting technology, it's about being self sufficient, and not relying on the outside world for anything. The phones are mostly for business. But they'll use them for Internet to get to Facebook and YouTube too.
It's also worth noting that the horse and buggy thing is pretty common but I've never met an Amish adult who didn't at last have access to a pickup truck.
Most of those business are Amish owned and run. Guy I knew had three or four giant pickup trucks, generally he was towing pigs to slaughter but he would cart anything they asked him to. They didn't trust the English to handle their business as far as they could throw them.
It's worth pointing out that the guy with the cell phone and pickup trucks also believed the world was flat. He was not a flat earther the way we think of one, and wouldn't know what that meant if you asked him. It just happens to say in the Bible that the world has 4 corners, and so it must. As, according to him and almost every person in Amish communities everywhere, the Bible is literally and 100% truth.
