I'm not familiar with the Cypher system mechanics so its hard to say. But I can think of crunchy RPG systems, like Lancer or Shadowrun. And I can think of complex board games like Twilight Imperium.
For many people who enjoy these, the complexity is part of the appeal. A simplified version of it doesn't give them the same degree of tactical and strategic options. The complexity is not there to exclude; it's there because it is fun.
And there's
also a difference between "this game is complex" and "this game is meant for people with a college-level education."
Complex, in RPGs, typically means "lots of moving parts and things to remember." It doesn't necessarily mean "requires a lot of math." I finally finished reading Ryuutama last night, and boy does that have a surprising amount of complexity to it, and that's a low-key game designed for people new to the hobby. It's
very serious about resource management--the Food and Water sheet is
separate from the Items sheet because of how it needs to be tracked. And the GM not only has to do all the typical GM stuff but
also has a GMPC to run. The only
math was rolling a pair of dice, adding them together, and maybe adding a +1 or +2 modifier. And that's 2nd grade math (I think; grade school was a long time ago). But there were a lot of moving parts and things to remember to play the game, much more than you would expect for a game that's about regular people traveling and taking in the beauty of the natural world.
(It does seem to have decent journey rules, though.)
Likewise, I'd wager most people would consider World of Darkness games to be fairly complex, and the only math that's involved is "count the dots and roll that many d10s."
The context, in this particular case, is about roll-under and roll-over systems, and ascending or descending AC. It's been noted that role-under modifiers are often confusingly and inconsistently written, and that it's provably faster to add than to subtract. So saying that the game should be specifically made and marketed to people with a college-level education because they
should be able to understand roll-under and descending AC--
that's gatekeeping.
