Not really. It's company culture. It does not have to be that way at all, and is honestly a symptom of poor leadership and a misunderstanding of roles on a team.

I disagree with having a culture that makes people afraid to submit a pull request because someone might help out and fix a problem with it, or make it better. Being angry comes from misunderstanding and fear that a developer's standing will be diminished because of the rewrite. A developer being angered by a correct or better rewrite is a symptom of bad leadership and a toxic culture.
