TBH, I never dug into rational wiki. However the timeline is fairly accurate from what I watched what happened to my friends both in the game industry and my former friends that were gamers (hint, i worked in games when this shit was unfolding).

Unfortunately, no other "timeline" source exists, with Wikipedia starting its paragraphs of history with Zoe Quinn creating Depression Quest, and many many other articles starting there as well. Some people like to attribute a slightly earlier event of a handful of journalists critiquing gamers over their reactions to the Mass Effect 3 ending, but that doesn't really fit with how quickly things snowballed after "The Zoe Post".
