There are four panels to this meme.
In the first two, a bearded man is seen saying, "Hi, I want to install your OS on my computer". To which two people, Apple and Microsoft say this, "NOO! You must pay me $10 then sign up for an account and consent to us stealing all yoour data and looking through your files!!!!!
In the last two, the same bearded man is seen asking the same thing to another bearded man, who replied with, "Done". This new man has Tux, the mascot of Linux, and the logos for Arch Linux, Debian, and Ubuntu behind him.
