Subjectivity is weird thing, especially because of the way it's been wrongly adopted on the internet. The whole 'subjectivity is great' stuff comes from modernist conventions and the whole post-structuralism thing and basically it's in regard to making as opposed to viewing.
Take the writers of the time like Kafka or Abe. The whole existential fiction thing based in a hyper-real world made out of introspection is the result of a subjective take on the world on their respective parts. However, to appreciate or discuss their produce you have to look at them objectively because otherwise you're not looking at them at all.
As far as Dugtrio here goes. he's got the Pele hair and it's clearly referencing pic related and by extension the entire teen culture of the era its design is based in. There are a lot of cultural evolution (memetics) designs in the Alolan forms - Raichu the most obvious - so it's not exactly out of place for a species to have adapted along with social norms, maybe in part to avoid being 'whacked' for being trendy? It's pretty fun, really.
Criticising it based on an associated had by the viewer is unfair since that association doesn't belong to Dugtrio, it belongs to the viewer and is therefore a projection and not a valid complaint. There's no fault in the design itself and it is certainly better than that Vaporeon things in the OP or pretty much any 'fakemon' - and that is a result of having criteria to work within and significant amount of work and research over a period of time as opposed to "I drew a thing, pls call it an art and a Pokemon too" which is the only thought process that can lead to a 'fakemon' even existing in the first place.
