Sorry but I don`t see the problem... I guess you try to claim something about a thing u don`t really know anything about.
Let me explain some stuff
Live editor, Fixer can (allmost) just change setting stuff for the next map. Other tools like DEM can change meanwhile u play. All these settings will of cource affect all players.
Now if u want change some other things than just the normally settings u must use another tool. Its like 100 free ones of them or even more... So the hackers wouldn`t use Fixer to do it.
Ah I might know what u think now
... Fixer is also a server side only tool, so u can`t join a server and change the settings... (For client side I guess the only working thing is the public message thing. Well don`t use the program on client side anyway.)
Or do u actually say there is something bad about that the host can set the score limit to 100 instead of 20 for the next map? Or do u mean some of the other settings (also u r an alone figher against this program noone hates it
)
