The alarms – part of the US emergency alert drill that the government carried out on 4 October – drew the attention of the community elders in Ohio
Correct. Amish are Mennonites who shun other Mennonites. The elders of their church decide for the local congregation what is and isn’t appropriate conduct. If you disagree, you are shunned.
I know this is pedantic, but that's just not right. Amish and Mennonites are generally distinct. One group does not belong to the other, though some groups in the middle claim to be part of both. Regardless, the umbrella term for both is "Anabaptist".
If the congregation down the road disagrees, those folks are shunned.
I've not known there to be much animosity between neighboring groups, but I guess I haven't witnessed an Amish church split up close. I know they happen though, but all Anabaptist groups in my area are quite friendly with one another.
Shunning seems to be more of a way to have their own members conform to their local rules. They really don't care what others in the community or neighboring Christian groups do. I think it really is a control mechanism -- e.g. "Do things this way or you are going to lose your family/friends/community support".
(Source: My dad grew up Old Order Amish, his family was kicked out of the church (over some farming rules). My grandpa transitioned to be Beachy Amish at some point, while my dad joined a (now progressive) Mennonite church that I grew up and remained in for a long time)

Well, Jakob Ammann, who the Amish are named after, was a member of a Swiss Brethren church (now called Mennonite) who didn't think his Mennonite brethren did enough shunning (a core principle of the Swiss Brethren).
So he formed his own church. Eventually members in his church (surprise!), shunned him over some different differences, as it happens when you join a group with all the cantankerous people. And it continued so on and so forth.
The distinctions might be in practical matters that arise over time--like fabrics used in their dress, use of buttons vs hook fasteners, or use of technology, or use of English vs German, but theologically they're pretty much identical and these differences are just natural things that happen over time.
An Amish church split is really just two groups mass shunning each other. There's no real difference.
And I'm aware it probably doesn't seem like that closer up, because I'm speaking very abstractly. But I can't see how anything you've said disagrees with what I've said.
And, I want to say I do appreciate hearing your experiences. For the record: I have a degree in Bible, did some post-grad study on church history, have some family members who are Mennonite, and grew up pretty close to a large Amish community.
