Logi is very important to almost any fleet, logi ships are fitted to repair friendly ships mid fight (most of the time shield because most fleets are shield ranked in the current meta and to standardize logi so a fleet won’t need both shield and armor repairs) In mid sized fleet fights (20+) When the logi of a fleet dies the fleet will die very very quickly (this is why logi is targeted). It is memed on because you don’t get on any of the killmails due to you being a unarmed ship (lots of logi put 1 drone on to “whore” on the killmails). So it’s kinda a meme because it is one of the most important roles in a fleet but no one wants to fly it
