I'm sure black just didn't know it was a draw, they played on thinking they would win on time. Which if it were true would be a perfectly valid way to win, it's not your opponent's fault you didn't manage your time well enough to get the mate.
Where does it end? If I play a 5+0 game, spend forever on a few moves and am low on time while my opponent still has 4+ minutes on the clock but have a positional advantage, should they just resign? Why do we have time controls, if you should just get to ignore them at your will when you feel entitled to a win?
How do we know you would still have the positional advantage, if you had played within the time controls as your opponent had? Or who can say they wouldn't have the advantage, if they had managed their time worse than you? It could be the difference in a potentially crucial mistake.
No, it makes no sense whatsoever to cry about losing on time controls you have agreed to. This particular situation is funny because black clearly had no idea about the draw rule, they were probably just as annoyed at this result as you are. But that's not because there's any sympathy to be had for your failure to win the game.
