Do you remember what Linux was like before the big corporations started contributing/supporting it? Just getting X11 working with your video card and monitor could take hours or days. Setting up a single server could easily be a "project" taking weeks. And god forbid you ever had to update it.
That in particular was thanks to the X.Org foundation. And while it made things easier, it didn't take "days" setting up a graphics, it took hours at most. And setting up a server didn't take weeks, it was an 1-2 day task at worst.
