For me it would be a play off of something like this: https://youtu.be/2zfqw8nhUwA
Go for giant big brother spying on everything you’re doing imagery. People following blindly passing spray painted symbols of Linux on the walls of the dystopian streets as they look down to their range of electronic devices that read “your personal data has successfully been uploaded to the Big Brother thank you!”
Switch to a man staring at his laptop. It’s clearly Windows and has a plethora of messages layered across the screen like, location services turned on, targeted ads turned on, forced update starting in 20 seconds, his age, income, medical history, terms of service agreements, cookie history, internet search history, Cortana recording, webcam turned on etc. A young person walks by and hands him a USB stick with Linux written across it and says to the man “you do have a choice”.
Screen goes to black. Bold text - “It’s time to take back control of your privacy. You do have a choice in an Operating System. Demand Linux!”
