Well, quoting from that message, "If it's not ready, you send patches around". I think the big difference is that I'm willing to take patches that aren't ready and get them ready, whereas I'm sure Linus usually pushes back on the contributor to clean up their stuff. And I do think merges are super useful in a lot of cases, but Linus added `git am` too, and I like using all the tools at my disposal when they fit.
