Probably a fairer characterization.

Well, I'm even skeptical of features that paying customers want. But
that doesn't pay the bills. ;-)
While complexity has super-linear cost, not all features introduce
significant complexity. It's very much a function of the architecture.
In a highly partitioned, loosely coupled system, adding a feature that
interacts with only a single other component in a trivial way may be
quite simple. In a monolithic system, adding a feature that permeates
the system may be so complex as to be unimplementable.
The features to avoid are those where the complexity cost outweighs the
revenue. If only we could evaluate this properly! ;-)
