To answer your second point, science has a process for disseminating new findings. It's not perfect, but it works. Organizations that scientists work for do pay attention to those sources, discoveries do get patented and productionized. I encourage you to conduct some research: See how many people were talking about mRNA vaccines and gain-of-function research on social media before COVID vs after. The lack of social media coverage didn't affect the science or the scientists, who had spent the past decade conducting research on the subject.
I will maintain that Twitter/X/Bluesky are not part of the scientific process, nor should they be. These platforms do not encourage objective thought or reasoned arguments.
