In the context odds are that Ace is using “orders of magnitude more” simply to convey “multiple times more”, or “a fuckload more”
That said I always understood orders of magnitude as log rounded to the units:
log₁₀(73M) = 7.86
log₁₀(2.1B) = 9.32
9.32 - 7.86 = 1.45 ≃ 1
If you’re rounding it to a single digit you’d get 1, or one order of magnitude. It isn’t too far from being rounded to 2, if Reddit shrinks back to 66M.
