Just because he wasn’t an engineer, doesn’t change the fact that he forged Apple into what it became,

I think the big complaint about Jobs is not the lack of engineering skills, but that he got where he did through deception, taking advantage of people, and often treating folks like garbage. Many of us view him as unworthy of celebrating, because the ends don't justify the means.

(There's also the fact that what Apple became was not all good, but perhaps that's a separate discussion.)
