If there's one technology ALL Amish communities agree on — it's internet. No. Completely. No exceptions.
Why
Phone can be limited (booth in field, 10 minutes). Internet can't. It's infinite. Pornography, social media, news, ads — everything Amish protect family from for 300 years. In one device. In a pocket.
Business
Problem: clients want to order furniture online. Solution: English middleman (takes orders online, passes to Amish by phone or in person). Or: English neighbor's wife runs website. Amish isn't online. His furniture is.
Youth
Rumspringa: internet accessible. Most try it. 85-90% later give it up (along with baptism). The 10-15% who don't return — possibly because of internet (can't give it up once tried).
