This was a reply I posted on "What should I say when someone says they "don't have anything to hide"?" In ask Lemmy a week ago, and I think it's still applicable here

They don't choose what they need to hide, if their government outlaws woodworking tomorrow, then any carpenters today go from "having nothing to hide" to "I need to hide my entire career and hobby" overnight and in their sleep.

And then the government threatens Facebook to hand over messages from any user suspected of woodworking, and then they get persecuted and arrested

The government threatens Google to hand over all browser history from suspected woodworkers, Apple for all iCloud photos from suspected woodworkers, Amazon for all woodworking related purchases

It goes on

If the carpenter cared about privacy from the start, then the government just wouldn't be able to find them and arrest them for simply woodworking

But the carpenter didn't care about privacy, they "had nothing to hide" yesterday, so when that law goes into effect tomorrow the government will have a really easy time finding them
