Doubt sincerly any exec or manager ever belived the easier and cheaper motto !
In opposition to what has been said in this thread their IT teams are very good and have raised (in vain) warnings against GCP since the beginning.
The official motivations for the GCP move as given to us, plebs (already mentionned in other comms) : - Financial move from CAPEX model (hosting own DC) to OPEX. - Transfer of responsability in case of fail; you can charge ($$$) GCP for downtime, could't really do that on your own teams. - Focus on business value and not on IT. (IMHO all of them are wrong, beginnig with the last one : you design & assemble planes on computers; IT is obviously part of your core business model, even a strategic one !).
And about the why GCP vs a french local actor the answer was because of tech maturity.
The 'easy and cheaper' is tech propaganda, this never was part of debate simply because it's false and we all know it, even the high execs in their ivory tower. Same thing as AI : haven't seen any big EU firm lay off big chunk of people to replace them with IA whereas in the US all the big ones already fired AND got the people back; US believes in it's own propaganda, EU doesn't ! Noone here thought we could fire sysadmins by moving services to CSPs, that always seemed like fake ad and reality is here to prove us right !
