You're using the strict sense of the definition and being overly pedantic. All of those games have the concept of "runs" where you encounter procedurally generated environments and empower your character with proceduraly generated items. That is quite literally the gameplay loop that was borrowed from Rogue. "Roguelike" is a genre descriptor much like "FPS" is a genre descriptor. It doesn't have to tell you what the graphics look like or how the game is played--no need to gatekeep the term.
