First of all, just to clarify, sort of disclaimer. My answer is not and cannot be taken as official reply from SIC.
From what I see (as staff), the maintaining of the circuit is "scarily" high. We can not deny the fact that SIC is one of the best circuit in the world and the other fact (which many of us do not know) that other tracks which is close to SIC in terms of facilities, charge way high than SIC does. Even other smaller track in the region charge more than SIC. And them, with lower maintaining cost.
Nobody likes price increase, me includes, but it is invertible. SIC might not become one of the best track in the world if we can't maintain the state of track as what it is now. But of course, everyone has the right to voice out their feelings and in SIC case,
please channel it to

SIC's CEO himself will read that.
