Yes well ignoring the cucked naked mole rat in favour of something significantly more cute, "my Charmander is weak because it lost to a water type (Poliwhirl), ergo I abandoned it" is probably one of the stupidest reasons the anime ever gave for a Pokemon getting abandoned. I get the guy was supposed to be lazy scum who just expected Pokemon to be strong without having to put effort in but still. 
At least the asshole who mistreated Cyndaquil had a somewhat more understandable reason in that Cyndaquil had legitimate issues getting its back flame to light and was thus nerfed half the time. Still an asswipe but I could at least see the reasoning there.
