Why C for the Open Source Movement?

["zeta_no" <olivier_henley@hotmail.com>]

Hi to all,

Can someone explain me the reasons why the main actors of the Open
Source community didn't choose Ada instead of C to write the core
elements of their systems (Linux, Hurd, FreeBSD etc...) and most of the
critical applications that come with it if the main goal was to provide
a real alternative to the "proprietary clan".  Would it have reduce
significantly bug list for all devel. projects and assure much more
reliable applications?  Isn't the Unix tradition based on well crafted
design mecanisms?  Does its traditional ways became so heavy to prevent
adaptation and or renewal of its philosophy through time?

Hope I do not make a troll of me,
