cultural and political will to prevent it

Well the EU and California are. Just yesterday I was reading https://www.lesnumeriques.com/informatique/une-premiere-victoire-polytechnique-claque-la-porte-a-microsoft-365-et-choisit-le-logiciel-libre-la-revolte-gagne-les-universites-n243905.html which is one example among many, here one of the most famous French engineering school switches away from Microsoft due to lack of GDPR clarity. Numerous administrations in the EU do the same. Yes it slow, yes it's not enough BUT it's something. I can't say if the momentum will grow and transform to a mass exodus, or if it's not a real trend and my bias highlights what I hope to see. Still it is happening.
