It's possible the 49 Euro is cheaper than a single train ticket, let's say 100km, between cities. It's very much cheaper for anybody communiting daily, a no-brainer to switch to the new ticket.

Some cities and states offer additional discounts, e.g. for seniors or the disabled.

The 2022 test mentioned in the video was 9 Euro per month. At that price it was cheaper than taking a bus a couple of times. It existed as paper version, too. States, federal government, local public transport agencies (there are many) fought all winter what the new price should be. Anything from 29 to 99 Euro was discussed. It's an expensive program.

Germany also has a ticket that covers all trains including high speed trains. It's 4339 Euro/year (or 7356 Euro for first class seats). I know several people who bought the ticket for their commute or where the employer gave such tickets to employees (instead of company car).
