Modularity isn't a mere "site effect" of OO: it's one of the main motivation factors that have lead to OO.

In fact, the main problem with these anti-OO rants made by procedural purists is that in essence they all boil down to claiming that basic OO features that are a part of any OO language can be reimplemented in procedural languages.
