@ShadowJonathan I have a special hatred for ads in the commuting system.
1) After rent and food the train pass is already my largest monthly expense. I pay more for it than internet and electricity combined.
2) Unlike most other ad selling places the income sources for the commuter system is public information. Ad revenu is like 1~2% of total income. IIRC it’s lower the rent for all the stores + vening machines in the venue.
It makes absolutely no sense that those ads exists.
