I've seen you mention the oil heiress thing a couple of times. The heiress in question is Aileen Getty. She helped found the Climate Emergency Fund which is basically used to fund nonviolent climate protests like these.

The emergency climate fund also supported the Dutch protests against the fossil fuel industry that ended with the Dutch government proceeding with a plan to end fossil fuel subsidies.

The emergency climate fund has had some success against the fossil fuel industry, so I don't think there is any evidence that this thing is a psyop to get public opinion to be against climate protesters.

It's very possible that Aileen Getty actually feels bad about how her family gained its fortune, and she is trying to reverse the damage by donating to these causes. If this was a fossil fuel industry psyop, they would do a much better job at hiding who was funding it.
