I am definitely guilty of this, in case anyone wants to call me out.
Look, there are lots of ways in which a game can be made complicated. Rules can play many roles. The devil is in the details. It is genuinely worth it to sometimes take a moment to look under the hood and see what kinds of rules are in the game before dismissing it.
Some games have lots of rules but they're fairly intuitive (once you know how spellcasting works in Ars Magica you can start using it quite naturally). Some games have relatively few rules but they are difficult to master (Burning Wheel famously takes at least half a dozen sessions before you even get a grasp on it, they say). Some games have lots of rules but they're all built using the same core ingredients, so once you learn the "Rosetta Stone" mechanic then everything else falls into place (most universal systems rely on this, like Savage Worlds or FATE. I would argue D&D 5E does it pretty well. It's very "rulings over rules" friendly). Some games have a ton of rules that are all disconnected and are each a subsystem that you have to learn separately and it's a pain in the ass (sigh... Fantasy Craft).
However, I want to put the spotlight on very specific types of mechanics that, yes, are all more rules than you would ordinarily need if you were just running something like B/X D&D, but aren't necessarily all equal in how much they truly complicate or restrict the game.
