I remember finding Rotom in Diamond and thinking it had to be some kind of minor legendary Pokemon since it was off in some side location with some strange events around it and just one of it was available, via a battle you initiate much like battles with legendaries. It was cool, really felt rare and special, even kind of spooked me a bit as a kid wandering a haunted house to find it while playing the game in secret under my blanket way past my bedtime. Then in Platinum you could shove it into appliances and it'd take them over as its own, really upping the special feeling of it. Fast forward to Sun/Moon and it's inside your Pokedex, quipping and pestering you, and it loses the mystery and magic it once had as a weird ghost that could hide in your housing wires and possess machines--now it's out in sunny not-Hawaii, treated like a funny gag--they say it's rare to have a Rotomdex, at least, and sure enough you don't see other people walking around with them. One game generation later, it's inside a phone. Everyone has one. It doesn't talk, it doesn't act of its own volition, it doesn't feel like it's actually a ghost possessing something. It's just not special anymore. It's basically just a sticker on a phone to justify it levitating instead of having a phone-holding pose/animation.
In a way, this mirrors what
>>58500296 said--with the proliferation of smartphones in real life, once exciting technological possibilities in the Pokemon world are flattened into boring mirrors of reality, and with the proliferation of Rotom in the Pokemon world, we out here in reality can't help but see it as boring and vaguely annoying now.
