You can prevent that by making sure these people have a lot to lose. Which means you start by paying them enough money.

Wait, European you said? Never mind. Only politicians and the very rich deserve money is the law here.

The owners of European clouds are people who were very, very wealthy before they ever started doing cloud (Xavier Niel, the Klaba Family in France, Hetzner (is also a German family name), Deutsche Telecom/Swisscom/A1 Telecom) and none of them have a reputation of decently paying anyone, whether we're talking software developers, system administrators, SREs, security guards, managers, ... and, of those, only Xavier Niel was not swimming in money when he was born (he was still very comfortable at a time when that was not at all common)

As are most politicians. For example, Ursula von der Leyen is a member of a wealthy German family that was part of the aristocracy in Germany. Her family's money survived WW2 in Germany (everyone in Germany and North West Europe knows what that means, and it's nothing good). Her ancestors belonged to the nobility of the Free Imperial city of Bremen, allied to the Holy Roman Empire. Nobody in her family has ever lacked for money for 20 generations.
