I also see genwunners mention these Pokémon a lot just because they're the easiest to attack and to compare unfavorably to the old Pokémon.
Take a French vlogger Cyprien for instance. In one of his videos which was a series of rants about different videogame franchises, he mentioned Pokémon, saying something like "what happened to the designs?", showed a Rattata saying "We used to have this", then showed a Garbodor and said "How we have ridiculous stuff like this". Quite an unfair comparison, if you ask me.
