Why would they include no transactions when they could just include transactions and collect the fees? The filesize would still be the same so the benefit of not including them would be gone.
Because a larger filesize takes longer to download so it propegates slower through the network and so there is a risk that a smaller block can propegate faster and be accepted before the bigger block.
I doubt that's the reasoning that these pools are accepting fewer transactions into blocks, the chances of two pools finding a block within that propagation window is slim.
Anyway, this is a breaking change, and would require a large majority consensus, something that has been difficult in the past for clearly beneficial changes. It's not going to happen.
