I wouldn't want to support such a project with donations or by working on the program code. I couldn't participate in such an environment. I just don't see any connection between the finished program and the reactionary attitude of the project owner that it might pose a threat to the safety of certain people.
The issue with the community is one thing and how it should be dealt with, i.e. through exclusion etc. - But apparently there are people who wanted to use this software because it's good, but now don't because of that. So they're hoping for a fork or that someone will take it over quickly. That still doesn't make sense to me. If someone does feel uncomfortable using it, OK. But apart from that, I don't see any concrete effects on anything if you continue to use this software. Nor how the use itself supports the project or poses a threat to anyone.
For my part, I have no problem using software that was or is developed by someone who is reactionary. If the reactionary thinking is not reflected in the code (how also?), it is no different to me than importing the different dependencies in my own code, where I don't even know if the persons which developed it are not reactionary after all. It is one thing how to react to such folks but thats not what I am talking about
But I am happy to learn and I could also be totaly wrong with my point.
