OpenSource Software Plea (in French ;-)

I've written a long time ago a plea on OSS. 
I do not include it verbatim here, but prefer to point it: it has been written in 2001 (and I kept it jealously [shyly?] for a while) and it has been first published by the excelent DNG (DotNetGuru: an open-minded and highly "architechnical" site on .Net and its relationship with Java world, webmastered avec maestria). 
Then, if you feel like reading french writting, give it a try!
