I was specifically thinking of the "Metric Martyrs" who were jailed over refusing to display weights and measures in metric.
The law requiring metric didn't actually come into force until 2000, these cases were early 2000s. Note that the law to this day still allows for imperial measurements to also be displayed, but they wanted to display in solely imperial.

The situation another 20 years later is rosier, even the boomers have spent most their adulthood with metric, and they're dying off now.
