It's not about who discovers the technology. They're completely fine using others' inventions. The main difference is that they live by the motto "just because we can, doesn't mean we should."
They treat all new technology with suspicion because they are afraid of the negative impacts it will have on society. And it's not like that's completely unusual...think about how many people, even on HN, bash Facebook for the detrimental impact it has on human interaction. Lots of people have "unplugged" from Facebook. The Amish just take this attitude to the extreme, and make it a community choice, not an individual choice.
