A sample size of 200 is a 93% confidence level. The company is international, and so is the diversity. I guarantee we don't all have the same experiences and backgrounds.

Here's a counter anecdote to yours: the organization I work in has around 1000 people, I'd say about 30% easily know what 'rooting your phone' means, and at least 5% (probably closer to 10%) do it. Also an international organization here. Your sample group, like mine, is not good enough to come to any conclusions.

Sounds like your organization is not diverse, but more of a technical one.
