Maybe. But it's not obvious that they would benefit from cheap petrol.
Not maybe, they do. And noone wants their product so expensive that people starts looking for alternatives.
At a guess, they're probably happy to encourage continued reliance on petroleum, whilst the rest of the world is switching over to renewable energy.
In that case, we should definitely reserve judgement on the weird payment stipulations then. The oil industry probably hates that the government is doing this, and we shouldn't cast aspersions on them.
