It's Lidl's parent company that's launching the service, after buying a cloud provider. The headline is just stupid. It's equivalent to an article titled "Whole Foods runs AWS".
No. Whole Foods is one of many Amazon ventures, but not the most significant. Supermarkets (Lidl and Kaufland chains, mostly) are the main business of Schwarz Group.
It's more like saying "Google will do X" when it's technically Alphabet that spawns X.
