Absolutely not. Simplicity is _beneficial_ - as the author argues and assumes - but it is not the alpha and the omega of product and interface design. When something has both simple and advanced uses, both a default mode of use but also complex customizability, the design needs to balance the extent to which it caters to the different levels of use-cases complexity. Just simplifying everything all the way makes the complex uses entirely impossible or effectively impossible; and medium-complexity uses cumbersome and difficult.

The author of this piece (and perhaps the author of "Don't make me think", which I haven't read) respects only the simple desires of the majority of users. S/he does not respect the complex desires and needs of minorities of users, nor the potential for the majority-user to refine and develop their needs and desires.
