It’s a fantastic step forward, making commuting with public transport much more affordable for many. But another nice thing about the 9€ ticket was that it got rid of all other tickets for occasional users, too. If you’re using public transport just a few times each month, 49€ is too high, and you will still have to deal with 4x tickets short tickets, AB/BC/ABC zones, day tickets and whatnot. Which is unfortunate, as that’s annoying, and they have to keep the complicated ticket vending infrastructure in place as well.
