I think it refers not to large, organic cations, but to small, inorganic ones

CH₃COO-
Anion of week acid

Was not enough to change your assumption?

I think it refers not to large, organic cations, but to small, inorganic ones.

I'm sure this is indeed the case, nevertheless: the hydrazinium cation is basic, inorganic and small...

What about (as mentioned in another post) [Al(H₂O)₆]³⁺  [Al(OH)(H₂O)₅]²⁺ + H⁺? Does [Al(OH)(H₂O)₅]²⁺ count as a basic cation in this equilibrium? (It can also be acidic.)
