My view on this is that stick figures are not copyrighted. There are loads of stickfigures comics on the net its just the style of humour aswell which makes people think this is XKCD.
XKCD is great (and not overated)but so is zoitz. I’ll probably always like XKCD mroe but htis is great. (and maybe just because XKCD has been going for longer and therefore more variation of humour in the comics)
