Imo, any large company, even if started hardcore by linus and luke (and co), will always in the end be mostly created by all the employees.

The ownership of any large company should imo always be gradually moved over to the people who work there.

Worker coops are not a silver bullet and will always be corruptible in any way any other democracy can, but at least it has the possibility to be proper, in contrast to strict founder / investor ownership where you are at their mercy.
