Yeah miners benefit more from smaller blocks, so which would you prefer if you were a miner?
If I was a miner, I would think long term and realize that I would end up raking bigger fees once bitcoin goes mainstream thanks to lightning network allowing for trillions of transactions daily, but miners (specially chinese) just want short term gains, so we are stuck with what we have as long as people are too much of a pussy to UASF and FORCE the miners to follow us, not the other way around.
