I might be overthinking this but I find her wording a bit concerning if they weren't fully awake to this dependency pre-pandemic. Everyone knows where Microsoft/Google/Amazon/Apple are based and these companies generally are operating under their own names so it's not like a shady conglomerate who owns everything without you realising.

Anecdotal and hardly conclusive but I work in UK local government and we get a weekly email from our web proxy showing the top 50 domains by proxy traffic in that period. The usual split is something like 42 domains that are linked to US companies, 5 are UK companies with the remainder being the rest of the world (including the EU). That's been the case for years now.
