In a way its understandable: It looks flashy, “hackery” and is a complete departure from the Windows or Mac GUI which avoids an “uncanny valley” of usability. Also it is pretty easy to install (i would argue, even more easy than many mainstream distributions), couple that with the positive PR that it got by some Youtube people and you have a road to success for this distro.
Why? Just ride the lightning and live the hacker lifestyle!
(Just kidding… perhaps those people have an image of their Windows installation on some external HDD)
