I came to accept the NES and SNES acronyms and I really don't care if they're prononced as "ness" or "sness." But it bugged me when the Nintendo Entertainment System stopped being THE Nintendo and became the NES. I feel like it started around the transition to the Nintendo 64 because in school you would still differentiate between the Nintendo and the Super.
Then: "Hey, you want to come over and play Nintendo?"
"Yup. You got Turtles II?"
"Sure do!"
Now: "Hey, you want to play some Nintendo?"
"What, like the Switch?"
"Naw man, old school Nintendo."
"Oh, like the 64?"
C'est la vie.
