Bullying in Closed Source Software is also bad. Off course in Open Source more people have the ability to do this, compared to a more controlled environment like Closed Source. What do we learn from the mistakes described in the article? Don’t close your eyes, watch and don’t trust untrusted people. If someone starts bullying or is toxic, take that as an attack and warn them to get banned. It’s like saying bullying under politicians is bad. Yes it is. And we should not allow that. But that does not mean we should stop using or developing Open Source (or stop electing).
If people are really unhappy with the direction of the project and if they want to push specific updates they want see, they should just fork it and do whatever they want. And if it works, it can still be integrated into the “main app”.
