Agree. There is a slight truth in this, but it does not justify the risk to the fish which to me is much more important. I'll explain.
Bacteria as Geo said live on surfaces in what we term biofilms. They are "sticky" in a sense and they adhere quite well. Once one establishes itself, it multiplies by binary division, which means dividing into two new bacterium. So changing the water has no effect on this.
However, ammonia is in the water, obviously, so changing the water will reduce the ammonia (and nitrite later in the cycle). And some do feel that this inhibits the "cycling" because less ammonia/nitrite means the bacteria will multiply slower, since they multiply in direct proportion to the "food" source, ammonia and nitrite. But, any ammonia or nitrite in the water--and i seriously mean any--is detrimental to fish. So it is more important to reduce the ammonia/nitrite as much as we can. The cycle may take longer to establish, but the fish will be healthier.
Water changes of half the tank volume every day if ammonia or nitrite is above zero is very wise. And to further help the fish, use a conditioner that detoxifies ammonia and nitrite. They will say on the label if they do. These are effective for 24-48 hours, depending, so the ammonia/nitrite remaining after the water change will be basically harmless.
