Satellites are making a negligible difference here so we can safely ignore those. The Moon is the major cause of loss via the tides–that large-scale movement of water exerts a small drag on the Earth’s rotation and causes it to slow down. It’s a tiny effect–it’ll take tens of thousands of years to slow the planet’s rotation by a single second–but it’s sapping rotational kinetic energy nonetheless.
