As for myself, I do not do a lot of water changes, I am too lazy. I have a planted 7 gallons, with one 33% wc each 2 months, I do not have algae issues with it.

Whether it's EI or ADA (Amano) the water change is part of the overall system. Anyone can have a tank free of algae without a water change the point is it's usually a limited system. Regular water changes increase the range of light, plants, scape, etc. It allows more 'mistakes' we all do them. It becomes a more forgiving system.
