The bus companies which operate official lines for Verkehrsverbünde will get paid the same as always, they’re not affected by the 9-Euro-Ticket.
However, I fail to see how that business, which usually involves a time constraint and direct point-to-point travels, would be impacted by this kind of ticket.
Secondly, the 9€-Ticket is valid in all of Germany, so you could travel the length and width of the country if you wanted to. You'd just have to change trains a lot.
Apart from the fact that I'm opposed for principled reasons. If we want to make people's life easier, we should cut down on taxes, not engage in more deficit spending. Especially as the economy is headed for hard times anyway, for exactly that kind of reasons.
Are they also thrilled by "additional market distortions" like subsidized oil import and processing and road infrastructure?
Or should we remove all tax-funded infrastructure investment and go back to the middle ages?

Its surprising to me that someone would even consider bringing this up as a valid counter argument. Interesting to see how deeply Neoliberalism has seeped into western culture.
