Clippy, despite being a poor piece of software, was simply there to help you. It wasn't trying to privacy-r*pe you at every turn to surveil you, upsell you, data-leak you, silence you, etc.

The suggestion to change your profile pic to Clippy comes from Louis Rossmann, a Youtuber who promotes right to repair and right to privacy. Just to gain awareness of how many people agree with this sentiment.
