>So then why not have the same for IT infrastructure instead of outsourcing it to all these parasites?

Not a comment on Atos directly, but I am betting that its an opex/capex thing.

Government departments see ongoing maintenance as internal, opex driven activity and right size their infrastructure teams to handle the ongoing workload.

Government departments see a large implementation project as an opportunity to save money through capex. Rather than increasing their resourcing internally to complete the project, they send it to tender. The tender document will require that the vendor hand over to their internal team for ongoing maintenance and support at the completion of the project. No ongoing impact to department opex budgets or headcounts.

Even if it blows out by like 50%, they probably still save money by not managing the labor costs internally. And they can force the vendor to take a hit on some overruns.
