Well, if they supplied the source code then customers could validate it
and fix it.;-)

I think that any product which lacks source code is unsuited for use in
a mission-critical Linux server application. I think customers should
tell companies this. When things break, you need to be able to fix
them, and not listen to excuses about how it is somehow the customer's
fault that they used a version of Linux that works except for the
vendor's code. The paradigm has changed.....

You have my sympathies. I will restrain myself from telling you about
buying a Dell laptop, and having customer service tell me that they
would not provide me any support unless I installed the original
(windows) OS when I had a clearly hardware problem.....

I should have bought IBM and waited 4-6 weeks for their incompetent
(incompetent only in that they take too long to ship) shipping
department to build and send me my laptop....
