How do companies running Linux request new features?

An article in LinuxWorld asks a great question: What About the Linux End Users?

"If Linux were a proprietary operating system, then companies such as Gillette and Staples who might want to use Linux to run mission-critical applications would make any queries or requests to the vendor. But who looks after them in the Linux world, asks Dr. Bill Claybrook - how do such companies get the features that they want included in Linux?"

Side note: The design of the "regular" version of this article on the LinuxWorld site is horrible. I clicked to this story from Google News and had a hard time finding the actual story content. Yuck! There's so much other stuff at the top of the page that the content I came for is far below "the fold." They also have an iconic toolbar below the story's title that has a "Read Story" link. Clicking on that actually takes you AWAY from the story you just fought so hard to find. How exactly does that help you read the story?
