There is a key difference from "don't do premature optimization." "Premature optimization" suggests the scaled version is optimal. It might not be worth the resource cost to achieve it, but disregarding that, its the best.
Whereas "Do things that Dont Scale" is suggesting the non-scaled process may be the optimal one. For example (and this sort of thing is in the article IIRC), giving direct contact details to the CEO instead of a generic form that get's sent to some shared customer service/sales inbox. Way better process for selling your product. The inquiry form scales but its in no way a premature "optimization."
Another way of putting it is that SCALING IS BAD. Or to be a bit more nuanced, it's a necessary evil. It's complex. It's resource intensive. It creates distance between you and your customer. Of course business goals and environment may dictate it, but that doesn't mean none of the processes are degrading in quality. So its more like dont do "premature process degradation" than "premature optimization" I think.
