That is simple ad retargeting and has nothing to do with like buttons! Many ad platforms offer this feature and it’s fairly simple todo from a technical stand point. Really the technology that enables it is not even something Facebook built! It’s your freakin browser! If you don’t want to get retargeted, just start using a different one...vote with your browser folks! I can’t believe I am saying this, but the html web browser is not the ultimate sophistication! There was a world before it and there will be a world after! And what propels this process is users voting with the choice of browser!
