The speed of light has the dimension distance/time. Distance is a relative measure of space (length, height, depth), time is a measure of... time. When we talk about relativity, the distinction between space and time isn't very useful, so those are actually the same kind of measure. So distance/time is the same thing as distance/distance or time/time or 1.
I suspect this is precisely the half truths and cargo cutting you're referring to. Maybe you could explain what the problem here is.

True. We're talking about the prettiness and factors of the numerical values, and the terms in the original hyperfactorial don't have units at all.

*its
Usually people omit c because it's power can be inferred.
And then they fail to mention to students that they're just omitting the c, causing a hilarious amount of confusion, half-truths and cargo-culting on the topic of natural units...

Saying that the speed of light in natural units is 1 is like saying that one meter in SI units is 1.
(s, m, kg, 10) can be seen as basis vectors of a vector space. (Multiplication is "addition", power is "multiplication".) Another base of this vector space is (h, c, GeV, 10).
