1. I think some people are confusing the e-canalmapp smartphone apps and the Water-Way PC product - apps are £5.99/region for iOS and some Android devices.
2. Agreed the canals do not change like roads... but the POIs do and Water-Way publishes new versions almost every week. Also Nicholson don't provide supermarkets, doctors, dentists, vets, laundrettes, post offices, etc.... so £25 might seem a bit pricey but many don't pay anyway as they are providing the Water-Way community with updates.
