> It’s apparent if you watch the discussions across platforms, there are obvious shared talking points that come in waves.

How do you know what is "shared talking points" vs "humans learning arguments from others" and simply echoing those? Unless you work at one of the social media platforms, isn't it short of impossible to know what exactly you're looking at?

It could be, and you’re right that I can’t prove anything beyond a doubt. But there is an entire industry built around professionally manipulating public opinion for money, and the groups most interested in deanonymizing the internet are well resourced. Simple inductive reasoning will tell you that a portion of the support is likely astroturfed.
