While there is nothing wrong with the patch in itself.
It erases any replacement hosts file with the default, negating the effects of any hosts file updates you may have done to date.
It also blocks specific IP addresses. While I happen to trust the person in charge of doing this, I do not like this feature.
For me this is a classic power struggle, of which I do not care to be a part of.
The new hostfile released by Sabre and co includes KM's peer cache servers, but KM's dll excludes your ability to use Sabres servers. this is something I do not like.
