I was wondering which of the examples you think particular fall into this category of making the code more opaque?
I actually went into this with similar misgivings. A lot of "get rid of ifs" advice, particularly from OOP people ends up making things more complex IMO. However most of the advice other than the "Switch to Polymorphism" seem very down to earth and a simplification. Less about getting rid of ifs as if their mere presence was a stain on humanity and more how to rewrite what they are doing more clearly.
