To start a server with a MCSG would have been fine, but you can't just change something like that after one whole year.
It is like finding a free-to-play game that everyone likes, and then make it pay-to-play when there is a lot of people playing. The forum might even get spammed with different "it sais u nid a klient" posts.
Boba says it is a way around it, but it is not. Few people wants a client just to play a server, that even worked without it. Even more people go to The Hive, that means more donors there, more servers there and also more players there, so they get even more popular and full, more people donate, more servers and more players again, til mostly every SG player is there.
