I have no idea what happened during the early 2010s. I grew up during the late 90s (born in late 80s) learning about the internet and its philosophies. Allowing Free speech still is the hill I'd like to die on. But the new generation of people, even here on HN and the internet hacker personalities I used to align with have turned so pro-censorship that I don't believe I'm in a proper reality/timeline anymore.
During the 90s information traveled slower and those with large audiences took the time to research reports before sharing it with the world. And if it turns out that they were wrong, the correct information can be spread across those few platforms to everyone.
Now, misinformation can be created way faster than it can be discredited and there are a massive number of surfaces where the misinformation can live without being corrected.
