I think that’s a very idealistic view of FOSS that is detached from reality. In the late 90s and early 00s we were fighting the crypto wars, making DeCSS illegal, DMCA, EUCD. There was a lot of infighting between free software and open source proponents. Many FSF campaigns were very political. I got bashed by some other FOSS people I knew in ~2006 for using and contributing to CentOS because it was Red Hat-based (evil empire or whatever).
The difference is that social media is amplifying things a lot more and there is a culture of destroying people in public (made easier by social media amplification).
It’s really the same issue as outside FOSS, social media creates stronger bubbles, more extremes, more grifters, and more amplification of crap.
