Yea I struggle with understanding that explanation too. I think something that plays a huge part of this is personalities that group together. Most people understand how important social game is. All activists seem like they have no social awareness. Their only goal is attention. They take the idea that there is no bad publicity to an extreme. I really believe many of these activist are being organized and funded by the oil industry without even realizing it. I say that because why wouldn't they in this day and age. Its easy to funnel money to organizations secretly. We have proof they did this in the past.
Great website for anyone interested on this topic. Full of documents from industries going back to the 50s showing internal documents and memos of how they knew and planned to discredit climate action
