There certainly are more examples, and the free speech advocates I know do talk about the subject generally quite a bit.
One I just now remembered: Dr. John Campbell (https://www.youtube.com/@campbellteaching) has run into issues with this and has pointed out many other cases where established "knowledge" about Covid that we were previously not allowed to criticize, turned out to be objectively wrong. These disputes have resulted in many other people being censored despite later being shown to be correct, or at least reasonably justified by the best information available at the time.
This is someone who was proactively warning about the potential severity of Covid well before others, and advocating for proper hand-washing very early on (before more science emerged suggesting that skin contact is a relatively minor transmission vector). In the early days of the pandemic, he was complaining loudly about Fauci's initial mask rhetoric, arguing that the general population absolutely should wear masks and that production needed to step up. He's been doing serious medical content on Youtube for 17 years (sort by oldest to see) and first posted about Covid on Jan 26 2020 when awareness was still low and it was imagined that the virus had been contained to China and presented extensive detail on what little was known at the time (https://www.youtube.com/watch?v=aPvpfC7NfR0).
But now he mostly makes videos against "the establishment", out of frustration with their unwillingness to consider new science over dogma.
