It's not about my attitude but about yours - I'm talking about the way social structures work in most cases. If you aren't willing to prove you can cooperate with a group, why would the group be willing to cooperate with you? Stepping in with a replace-the-whole-UI idea is generally combative in nature and may engender combative responses. Rather than being surprised at the response, maybe think about whether what you did might cause it. By odd analogy, it's like you're starting a career as a traffic engineer and immediately demanding the road surfaces get replaced, without demonstrating an understanding of why the road surface is the way it is or why projects to replace the road surface tend to fail. (I'm not involved with the project, so my attitude doesn't matter and you don't need to worry about what I think.)
