Things are easier when you are writing to your peers within an established academic field. But all too often, the target audience includes people in neighboring fields. Then it can easily be that most people trying to replicate the work are non-experts.
For example, most of my work is in algorithmic bioinformatics, which is a small field. Computer scientists developing similar methods may want to replicate my work, but they often lack the practical familiarity with bioinformatics. Bioinformaticians trying to be early adopters may also try to replicate the work, but they are often not familiar with the theoretical aspects. Such a variety of backgrounds can be a fertile ground for misunderstandings.
Sure. You can't write to everyone and there's tradeoffs to broadening your audience. But I'm also not sure what your point is. That people are arrogant? Such variety of backgrounds can also be fertile ground for collaboration. Something that should happen more often
