It’s not clickbait. The Linux version of Steam consisted of a binary, as well as a script called steam.sh which could be used to launch Steam. There actually was a line in that script with a comment above it saying # Scary!. The script was not supposed to rm -rf the entire hard drive, but if something went wrong, exactly that happened.

Ok, thanks for the info. I started freaking out :D

Yeah, I’m sitting next to someone and I don’t loudly watch YouTube next to others. Guess I’ll never know how Steam did it. ¯\(ツ)/¯
