If the raw OSM map data is free why are you charging for the TT HD Topo maps?

What scale are the maps offered here?
The maps do not come in the traditional paper based scales of 1:50,000 (1:50K) or 1:25,000 (1:25K) as they are dynamic; the more you zoom in the more detail is shown (until it all appears). The TT HD Topo (aka TT 1:50K Look n Feel) map style offers ...

Can I use the map(s) on multiple devices?
