We're going to keep seeing this due to destabilization and political changes in the US. It drives nationalization elsewhere, even among allies.
This is exactly what I'm seeing in working with companies in Belgium, Germany and France.
It's not just about costs- managers are actively seeking to distance themselves from everything US.
We've stopped treating them like allies. Who's to blame them?
this has been happening on and off for ~10+ yrs. MS cost are too high and you need more expensive computers to have the MS sub-par experience.
the main thing that keeps people locked in is (a) "Im use to windows" and (b) MS gives them some special contract to keep them.
It doesn't help that Microsoft seems to be doing everything in its power to alienate Windows users.
