Schwarz Gruppe includes Schwarz Digits, which include StackIT. 7500 is the number of employees at Digits, which also includes online marketplaces like Kaufland e-commerce, so definitely not all of them work on the sovereign cloud.

Lidl is a grocery store chain, I'm assuming GP was talking about the amount of people actually working on the cloud.

Lidl has 375,000 employees. They have stated they employ 7,500 people in their digital services division.

Yeah, Lidl and Kaufland are store chains, with 14200 stores combined. 7500 employees is just Schwarz Digits, the digital services division.
