What else can be more profitable for a consulting company than shifting the entire IT of a city or a country between two largely incompatible solutions? :)
See that's the neat thing SH has (together with HH, HB and ST) its own IT consultancy. Public enterprise, not some public-private partnership, and 5300 staff a quite a bit more than what Munich's IT department has.
And yes of course Munich is corrupt what do you expect it's Bavaria.
Nah dataport doesn't make profit, or at least it's not paying out any to the states. It's about as close to a ministry as you can get without being required to pay government wages and there's not many in the industry who'd work for that. They don't pay as much as FAANG or even SAP but among the wider industry it's definitely competitive, especially if you don't plan on job-hopping and dodging lay-offs.
