I think that one might think that an example is relevant if it has repeatable properties.

WhatsApp might be so straight to optimum that no visible properties of engineering are extractable, besides that the engineers made no errors in their judgments.

Making no errors is something you want to replicate, you just don’t know how. Seen like that, the example has no value.

Personally I think that showing that it is possible had some value per se
