Server hosting is a free market, you don't like one, you move to the other. If there's no other, you start your own. It's simple as that.
As long as there are people playing on zabijaka servers, it means they're good enough. And don't tell me "there's no other like this out there" because we all know it doesn't take much to set up a good competing server. There are plenty of people around (myself included) that only if asked will be happy to lend their equipment and assist anyone in setting a server.
