Honestly, let SE make as much money as they can.

It doesn't have to make much sense, many places charge odd administrative fee(s) on bills. Some places even charge a fee to send a bill. Plus since when has SE applied logic >.> or the internet for that matter. If there was a shred of logic most of the threads on forums would never exist XD

And that's why we express our discomfort and give them our feedback. Hopefully they will listen, who knows, and it would benefit everyone (yes, even those willing to pay what they're asking).
