You seem like you've learned the right lessons, but more often I've found that learning just enough to be dangerous makes managers worse at this. Take the example in the article, where the developer who made a well factored application was "overcomplicating" the code. It's not uncommon for a beginner who understands the means of programming but hasn't been bitten by the results of bad design to make poor decisions for the sake of experience that need to be made up in extra work later. Having a manager who actively encourages solutions like "Why not just copy the entire method and wrap it in an if statement?", or "Can't we just comment out the existing code that's incompatible with this new feature?" can be demoralizing - if they're in a position to actually make that happen, it's even worse.
