Yeah, sure it's possible but it's quite different to actually getting your hands on the source as well as the version history of the source (why is this code here? git blame and you'll know why) and make changes to it if you want. As I tried to say, it's more of a philosophical and psychological (and practical) thing than actually being impossible. Reverse engineering is a valuable skill but it's not too fun when you could just look at the source, with variable names, comments and nice formatting. In some cases it might be a nice "puzzle" to solve but that's not how you want to learn how things work.
