It's very easy to snigger.
On the other hand - there are millions and millions of people in London who use Oyster every day for their travel and it just works (almost all the time). The real question they might ask is why doesn't it work elsewhere. You and I know this is because national ticketing is immensely complicated - but the general public don't know that (and why should they). So far the rail industry and DfT have been lamentable in explaining this to the general public.
Actually they do know. In today's Metro there is an article on train ticketing and how it's almost Byzantine.
How much of this is clamouring for simpler fares and an unwillingness to research cheap tickets (a sort of if
I can't have it, nobody can) is up to you, the reader, to decide.
The danger is that the rail industry will create another PR disaster - because as far as millions of London travellers are concerned (and remember the London market is a huge percentage of public transport users in the UK) the smart ticket problem was solved two years ago and why doesn't it work elsewhere?
The smart ticketing problem is hardly solved, indeed London is a special case in that most of it's major stations are barriered. Ditto for the underground system. Then consider the pink readers that are needed, the maximum journey time, lack of break of journey, continuation journeys and OSIs.
Smart cards are a long way off and personally I'd rather they were kept in London and other major cities which is only where it's required.
