I see they're replacing Greta Thunberg with a more attractive model. They probably thought Greta would look less like a slightly overweight 12 year old when she got older, but it never happened, so they've had scramble to for someone hotter.

She is there purely because they feel they can trust her to parrot the opinions of the rich old men. She is a young, pretty face for them to hide their own fat, wrinkled husks behind.

The only question is whether she is aware that she's an intentionally selected pawn or not, and it doesn't really matter either way.
