I think it's a confluence of factors:
1) Open source is more about interpersonal collaboration than it ever has been. The lone hacker throwing tarballs -- or patches -- over the fence is dead. Open source projects now more closely resemble "real world" software projects: a team of engineers using collaborative tools, working toward a defined shared vision with management and oversight. Major projects no longer follow the BDFL model, instead using incorporated entities like the Linux Foundation to direct development replete with boards and committees, leading to more "office politics" in how major decisions get made. A tradeoff for the greater continuity and community input a foundation provides.
2) Open source is more diverse than ever before, and becoming more so. More diversity means more perspectives coming to the table.
3) Fully 25% of Gen Z identify as LGBTQ. Among hackers that number is higher; it's likely a majority of late Gen Y or Gen Z hackers are queer. And a significant fraction -- again, perhaps even larger than previous generations -- are neurodiverse. With these identities comes greater awareness of intersectional issues, and greater awareness of oneself as a member of certain classes. Pretending that this is irrelevant to software work -- hsistorically, predominantly a white male dominated pursuit -- is a fool's game. There are going to be struggles and clashes as members of different classes assert their grievances and call each other out.
In short, this kind of "drama" is a growing pain of open source becoming a real movement that invites and incorporates diverse voices. We'll muddle through it and move on.
