Of course, if you and your group chooses not to roleplay skill challenges, then that's entirely on you. That's not a fault of either skill challenges or 4e, much as people can likewise choose not to roleplay their use of skills in 5e or 3e before it.
"Rollplay" is a loaded term that is often used in an insulting fashion to belittle mechanics, games, and people as playing in a way lacking of roleplay. It's hard to imagine that you are not aware of this highly charged and negative connotation of "rollplay" in your years here. To be clear, I think that even calling combat "rollplay" is belittling of the roleplaying that commonly occurs in this play.
