I wasn't sure I wanted to answer you but I will. Well most of our staff works voluntary (Meaning no real life currency - no $, no €) Donating to this server is what keeps it going, because trust me a WoW private server without donations is a monthly black hole for money.
Than again, who are you to judge if its poor job by the devs or not? Can you provide better things? This topic is absolutely pointless. @Rattle we have a user submitted patch section in this forum. Be my guest and give us something less "poor". And without being an administrator here all your calculations are just numbers so please keep them to yourself.
