I feel like this article is being critical about something without justly staking a clear claim about what the right approach is. In my experience, the benefit of DRY code is bug reduction and overall increased new development velocity. There is a whole class of bugs around similar behaviors that devs and product managers expect to move in sync which don't, because features develop over time and it was just easier to code separate small bits than refactor into a common code path. Yes, it can make readability harder to unify into abstractions and create the right configs or import steps. But the time hunting down and fixing the bugs, plus the drag on overall feature development due to having to write updates in multiple places and test for them is far worse to deal with for not taking that preventative measure.
