Now whom shall I believe?
Me, because Nescafe is wrong. What he probably meant is that it's not significant for gravitationally bound structures, which is true. Its effects are small at short lengths, and get larger at larger lengths. The largest gravitationally bound structures are still small compared to the observable universe, so the effects on them are negligible. Furthermore, what happens to gravitationally bound structures isn't the same as what happens to unbound structures. But that doesn't mean that there is no effect at all. There is, because gravity is gravity. Just like the gravitational attraction between you and me exists, but it's safe to ignore it.
