Overwatch seems to have a different culture than Fortnite. People might say "heh" if the play of the game is Default Skin Reinhardt using the Heroic highlight intro... but that's as far as it goes. Playing the game seems to give enough skins that nobody is particularly concerned about it.

From reading the comments, it seems like Fortnite players make fun of each other for not having skins, thus people are pressured into buying them. I am guessing that because the game has so much downtime, there really isn't anything else to do.
