The idea that we (Canada, any EU country, etc) can "easily nationalize" data centers running on bespoke hardware that we do not have a supply chain for, bespoke software which we do not control or have the source to, running workloads for customers as dictated by business relationships with a (now hostile) foreign company, with the descriptions of those workloads almost certainly stored in said hostile foreign companies local (i.e. foreign to us) servers... is absurd.
It's even more absurd to suggest that this can be done in response to the US becoming more hostile than they are today. By the time they are more hostile, we're talking about open hostilities. It's only safe to assume that they will have exfiltrated all the data they are interested in, and then sabotaged or destroy as much of the hardware as possible (as can be done remotely), making the data center next to worthless. And prior to nationalization it was "their data-center", they were entirely within their "rights" to sabotage and destroy it.
The time to migrate away from data-centers to minimize geo political risk is now, not when the current data centers operators are actively trying to deal damage.
