I personally have no interest in PHP or BDSM but I think really everyone who wants to participate in Open Source Software in 2017 should be paying attention to this along with other instances where people have been kicked/banned from projects alongside public accusations against them. Especially if you have been participating in online communities for a while, your conversations have probably been archived and are open to scrutiny based moral standards that are constantly changing, both in terms of who is applying them to the project, and changes in the views of each individual. And when I say your conversations, I mean both conversations that you've held in public-ish settings and also conversations that you believed to be private that could be forwarded or screenshot without your knowledge or consent. Or conversations where you believed you were pseudo-anonymous where your identity was later reveled.
Also, given international participation of many projects, the moral inquisitors may hold views that are significantly different than anyone you've ever met or interacted with in a non-technical setting.
I think the TV show Black Mirror should be shown in high schools as an educational video.
