Just like in our generation there will be people in our kids' generation who will want to know how the sausage is made and it will be a tragedy if the only way to do so would be to grow up, join a big firm and sign a NDA. Even for the others, an open platform means a greater variety of software for end users. Creating toll gates on the way to software development or suppressing software which reduces the platform owners's profit is not good for end users. Many people who will never touch a command line still benefit because a Finnish computer science student could decide to start writing a PC operating system of his own and that OS now powers their phone or allows others to provide online services on servers that runs that OS. If building iPad clones with an open hardware specification like the PC's becomes possible for multiple vendors I'm sure we will see a software ecosystem that will easily beat the walled gardens. The problem is that currently the number of firms that can build the hardware is small enough that they find it in their self interest to use closed specifications.
