Reminds me of the Steve Jobs biography. He was a notorious tinkerer. He obsessed over the design of Macintosh, the NeXT step cube, and a bunch of other products.
He also valued taste a lot. It seemed like the worst insult Jobs could have for someone was to say they had no taste. Other insults may have used stronger language, but it always felt that him saying someone had no taste was to say they were worthless and he had no respect for them as a human being.
No he definitely tinkered. Yes, his primary tinkering mechanism was "having others execute his vision," but like if that's not tinkering then neither is editing config files like the article author mentions, because you're directing other peoples code into configuration.
There's one story from Macintosh era where he spent weeks harassing one engineer over the calculator app: "it looks too bloated, it looks afwul, these lines are terrible.." until the engineer got fed up and said "here this is the Macintosh Calculator App: Steve Edition. You get to pick your font, your layout, your color theme." And Steve sat there for hours literally tinkering on a calculator app until he got what he wanted.
He tried to get Paul Rand to change the colors on the NeXT logo--who promptly directed Steve to go have s*x with himself.
There was one point in the Apple Store's inception where they had basically reached done, and Steve decides that he didn't like a certain aspect of it, which was essentially going to require them to redo the entire thing. So he did, and they started from scratch. I think it might have been the Carrara marble floors but I can't remember for certain.
I'm not saying I have immense respect for the guy as a human being, but he was absolutely a notorious tinkerer--a complete menace of one.
