From what I gather, corruption in this case means that civil servants of the Garante per la Protezione dei Dati Personali got business class travel when they should have flown economy class because the trip was under five hours (the established cut-off for upgrading to business class), and that they stayed in hotels that were better than the ones authorized for civil servants. There's also something about the head of the Garante changing the terms of his lease in Rome on an apartment that is directly adjacent to an AirB&B owned by his daughter, but my financial Italian's not up to understanding the full details. I think this is less the "point out Grok's deepfake" kind of corruption and more the "some civil servants think they're entitled to live better on the taxpayer's dime than other civil servants do."
