The @EDPS provided @nextcloud to bodies of EU, as e.g. @EFSA, #ECHA and @EUCommission all use MS-Teams/O365 and demand the same from member states. More than a year ago EDPS demanded, that EU bodies stop certain data flows to these products by end of 2024. https://www.edps.europa.eu/press-publications/press-news/press-releases/2024/european-commissions-use-microsoft-365-infringes-data-protection-law-eu-institutions-and-bodies_en
AFAIK Commission currently sues (did sue?) EDPS for this. I hope this gives a new take on the debate as now it is not "only" a GDPR-infringement plus some "alarmists scenario" but a very real threat.
