When did the term skeptic start to mean someone who "debunks" ideas that are at odds with the status quo? When did "critical thinkers" stop asking the tough questions and just decide to parrot the official narrative?

It seems that the definitions for these terms have been hijacked by people who demonstrate the exact opposite of their original meanings. People that now claim these distinctions are neither skeptical or critical thinkers.

Just an observation that's been bugging me for a while.
