But Jobs did exactly that! By streamlining the product line and eliminating unnecessary jobs, he turned Apple around from a struggling company to what it is today. He served the business and users well by doing this. He was also able the advance the technology further by having his team work on fewer things and do them really well.
The point is not that he cut 3000 jobs to place design above everything else. The point is that he made an emotionally difficult decision that did not necessarily put him in a favorable position in the eyes of many, but that nevertheless he did so in order to deliver on his intention of quality over quantity.
