The article about the Mennonite family becoming JWs is on the main page of the WTS website.

In the course of the article they give a little history of the sect but the juicy parts that would interest most of us here in "apostate land" are in the second half of the article.
Some snippets:
Start of the arcticle: ONE morning in November 2000, some missionaries of Jehovah’s Witnesses in Bolivia glanced out the window of their small home and saw a group of plainly dressed men and women standing nervously at the gate. When the missionaries opened the gate, the visitors’ first words were, “We want to find the truth from the Bible.” The visitors were Mennonites. The men wore overalls, the women dark aprons, and they spoke among themselves in a German dialect. There was fear in their eyes. They kept looking to see if they had been followed. Nevertheless, even while climbing the steps to enter the house, one of the young men said, “I want to know the people who use God’s name.”

Some Mennonite groups, determined to keep separate from the modern world, have moved their communities to places where local governments allow them to live without interference. In Bolivia, for instance, an estimated 38,000 Mennonites live in numerous remote colonies, each with different rules of conduct. Some colonies forbid motor vehicles, permitting only horses and buggies. Certain colonies forbid radio, TV, and music. Some even forbid learning the language of the country they live in. “So as to keep us under their control, the preachers don’t let us learn Spanish,” commented one colony resident. Many feel oppressed and live in dread of being expelled from the community—a terrible prospect for one who has never experienced life outside.
It was under these circumstances that a Mennonite farmer named Johann saw a copy of the Watchtower magazine in his neighbor’s home... He asked to borrow the magazine.
...
Some of Johann’s family began talking to their neighbors about the things they were learning from the Bible. ... Soon, ten of the family set out on a secret trip in search of Jehovah’s Witnesses and ended up at the home of the missionaries, as mentioned at the outset
...
A few days later, the church elders came to the home of Johann’s family with an ultimatum for the interested ones: “We heard that Jehovah’s Witnesses visited you. You must forbid them to return, and unless you hand over their literature to be burned, you face expulsion.” They had had just one Bible study with the Witnesses, so this presented a formidable test.
“We cannot do as you ask,” replied one of the family heads. “Those people came to teach us the Bible.” How did the elders react? They expelled them for studying the Bible! This was a cruel blow indeed. The cart belonging to the colony cheese factory passed by the home of one family without collecting their milk, denying them their only source of income. One family head was dismissed from his job. Another was turned away from buying supplies at the colony store, and his ten-year-old daughter was expelled from school. Neighbors surrounded one home to take away the wife of one of the young men, asserting that she could not live with her expelled husband. Despite all of this, the families who studied the Bible did not give up their search for the truth.
...
Cut off from their community, the families began making their own cheese. The missionaries helped them...
...
“It was difficult after we were expelled from the community. We would travel to the Kingdom Hall with sad faces,” recalls one family member, “but we returned joyful.” Indeed, local Witnesses rose to the occasion and offered support.
Gee...people who dared think for themselves and buck the overbearing system they were a part of are expelled and shunned. Now, what if they decide to study with some Catholics or Protestants after becoming JWs? What happens then?
