This depends on the context, though. In my open source projects, I have many contributors, so it's important to maintain a consistent style throughout (for example, naming conventions, so that the same data is always called the same thing).

A commercial software project will also have a 'house style' which all contributors are required to follow. It's okay to withhold approval on this basis.

What I think you're saying, and I agree with it, is "don't withhold approval just because this isn't your style".
