Not necesarly, some people actually want to play games on the last firmware, buy those games and have homebrew and cfwThats what i mean you really only want to update to play the latest games on emunand.
It may be the only way to update games for now but it definitely wasn't that way for other consoles and there will be a modable update system eventually.
And well i believe you should be banned from playing online with modded consoles and game saves. If you want to play online you should buy 2 consoles
EDIT: Is such a blowminding thing that there are people that use homebrew, cfw and buy games?
