> Your argument is that people had no existing profit motive to use dirty tricks to influence scientific results/data?
No, that's way too broad. I don't believe that, and I didn't write that.
Oil companies indeed had enormous incentives to obscure and confuse the scientific record of climate change. But hiring thousands of Taskrabbits to go around the world blowing hot and/or cold air on weather sensors would not have helped them: some of them would have been caught, and it would've been exposed as a hamfisted and shambolic scandal.
Oil companies had to do larger-scale, longer-term stuff like funding think tanks, lobbying politicians, and writing op-eds.
Now, because of prediction markets, the "attack surface" for interfering with scientific data collection is much larger and more fine-grained. The incentives for big oil companies probably haven't changed much… but now any random amoral idiot or degenerate gambler has an incentive to go find unguarded weather stations or water quality monitors, etc, and mess with them.
