The problem with British maps is that they are not produced each time routes change so you can't rely on them. In many British cities outside London route changes happen frequently so making maps up-to-date is impossible, but even with the regulated system in London route changes can happen at any time. In some other countries you get one timetable change per year (coinciding with the rail timetable change) and the map is redone at the same time. I stopped using printed maps years ago and swapped to pdfs as soon as they became more practical. Most European cities make online maps but I wouldn't think about getting a printed map and wouldn't be sure if they exist and where to look for one. Getting a printed map would be a lot of trouble for most people these days who are used to instant information. Popping in at a bus information office to pick up maps and timetables used to be a rite of passage for the enthusiast, but even they can't often be bothered in modern times. I suspect most young non-enthusiasts don't even realise bus maps are a thing.
I don't see that maps are especially "an enthusiasts' thing" - they're actually functional. They provide different information from a screen and fulfil a different function.
If I arrive on the train at a major European city which I don't know, or haven't been to for some time, the first thing I'd do is go to whatever sort of tourist information place there is on the station and pick up any useful information ... maybe a map of the centre of the city, and certainly a map of the public transport system - buses/trams, metro if it exists, and so on. How else can I orientate myself and plan where to visit in what order and how to get to places? Once, a few years back, when the place I was visiting had no bus maps available (Genoa - too hilly for me to get around easily without knowing the public transport system, ie having a printed map I could lay out in front of me to see how the system fitted with places I might want to go), I cut short my time there since I couldn't use my time efficiently.
Use of public transport should be made as easy as possible - and that has to include relevant maps.
(A related point. In this country too, there have been tourist attractions I've wanted to visit, but haven't done so because their literature and their website give access information exclusively for people driving there.)
