It seems like common sense, but all too often in the tech sphere people forget a really simple rule.
It doesn’t matter how correct you are if the way you communicate only serves to alienate those you seek to persuade.
Koha has fortunately been quite lucky in this regard 99% of the people involve understand that the project is about far more than code and that people are what really matters.
But it can happen anywhere even occasionally with Koha. It’s even more unfortunate when it is a goal people agree is well worth it. So people agree with the message but the delivery of it only serves to make people less likely to listen.
