The dynamic is not one in which when miners win, users lose. The issue is that users want more transactions per second and therefore want bigger blocks to be created, however, when miners create larger blocks, they have a hard(er) time propagating them to the entire network and thereby run the risk of their block being orphaned (someone else's block will be accepted first, and the miner's block and work done on that block will be wasted).

Oh I see, which is why Chinese miners would be especially hesitant about moving to larger block sizes, because the GFoC significantly limits speeds.
