I am not trying to really speak on others behalf. It's not just Pokemon, but I hear this a bit in regards to movies and games, etc.
Personally, I find the use cringe because it comes off as, I don't know, dismissive in a mean spirited way. Embarrassing is, my pants falling off randomly in public (which has actually happened to me lol ) or if my kid ever through herself onto the floor throwing a tantrum in the middle of a market (thank god she never did that).
Devs put in a lot of work, often thankless work, and often speak passionately about something, and the whole "they should feel embarrassed" comes out. It leaves a bad taste in my mouth, as if they were a child that needs to be punished or something. Don't know. Comes off mean spirited, instead of legit criticism. Their open world designs need work to match their non open world designs, for example, is legit critiscm. I even persoanlly agree with that. It was jarring going from say, the fairy town in Sword to the Wild Area. But I also don't take it as some affront.
