The main issue here must thus be one of ethics. I had a look at the maps from Garmin, and they are, to put it mildly, a bit pricey. I am aware that the majority of the maps on this website were made via authorised methods, utilising tools like OSM. I believe that was my primary worry. I shouldn't be bothered by this, probably. I'm not sure; if anyone has wise counsel on this, please share. Thank you for your thoughtful response.
