Maybe it's like this:

Sabine's has a day job as a Youtuber, and she makes her videos from that perspective. She speaks her mind, makes a decent living, and educates some science nerds on the way. Seems pretty nice.

From the perspective of accomplishing institutional change in the academic physics world, this is does nothing. The institutional powers don't react at all to a complaining influencer with an Einstein doll.

And I suspect she's perfectly fine with that. Overturning the Physics establishment is a near impossible task. I would leave that for those mad enough to try.
