First of all, Cringely doesn't even attribute this information to a real source in his article, so there is no way anybody can even verify this. He just says two good sources, which mean almost nothing.
The second thing is, this sort of planning happens all the time at every big company. I know most of the slashbots probably never worked a real job, but it's good planning in the corporate world to know plan for where such a huge share of stock is going to go.
In short, this article is such a hack job looking for biters, I don't even know why it was posted to slashdot. Wait, actually this was a perfect article for slashdot.
