I found her situation quite funny actually. Because the media latched onto her and cancel culture is or at least was at its peak, these corporate powerhouses and world leaders were forced to sit there around the world and listen to a brat child shouting at them and then at the end they would have a competition to see who could stand and cheer for her the loudest, apparently.
It was all just a show of course... those world leaders and especially the corporate guys don't give one fuck about Greta and almost certainly talk trash about her immediately after she leaves the angry stage.
