very disappointed to see "easter-egg" in a free-software

Dear Sir,

During our last meeting of the "Liege Linux Team" (LiLiT), a member 
shows me the game "starwar" available on the openoffice calc.

It's a pity to fall down on the same problem as commercial softwares. 
One of the argument for the open source software is, "this program do 
what he says to do, not more".

I understand a program is more and more heavier to add functionnality or 
possibilities I probably never use (but others users can use). But I 
cannot undersand to add 'hidden' functions , for the fun. It's far away  
from the alternate way we promote.

Please think about the open-source philisophy before to add this kind of 
thinks. If I want a small game, I install a game, If i want a 100% 
serious office program it must be 100% serious.

You do a fantastic work for the future of the world, congratulations!! 
Please, don't fall down of so a detail.

Best regards,
