I haven't used social media in over a decade and I change my mind all the time. Changing your mind is a good thing for a thinking being.

Social media figures aren't changing their mind in the same way, they are changing and optimizing their public performance.

Professional social media is a paid performance. We understand that Tom Cruise is not really a highly skilled jet fighter pilot but a well paid actor playing the role of one. No one cares what Tom Cruise thinks about Ukraine/Russia air defense tactics. This gets hidden in plain sight with social media though and why social media is hyper stupifying.

Right, it's not so much "changing minds" in that they probably aren't thinking about much very deeply... it's more like "changing to suit the popular narrative direction"
