We've been auditing our services recently and looking at whether and which services ought be moved or diversified from US vendors. Obviously we're not going to lift-and-shift on purely ideological grounds. That would be disruptive. But for new services, or small - easily moved - things, then it's certainly a consideration as the year rolls round and contracts or subscriptions are renewed and we look to rebalance our spending.
The most depressing thing as a UK firm is that whilst there are many decent-ish European cloud and mail vendors (OVH, Hetzner, Scaleway, Tuta, etc) there's a real lack of UK providers. If you're a French firm, you could pretty easily turn to an entirely French stack for hosting, cloud services, S3-compatible backup storage, marketing email, etc, etc. Same if you're German or Swiss. We have some in the UK, but not the same diversity that France or Germany have (never mind France and Germany).
This isn't a problem as such - I've no objection using a French or German provider - they have UK regions and so on. But for the "self-serve" experience where you plug in some card details and crack on (akin to AWS/OVH/Scaleway), the UK has surprisingly little on offer (other than a seeming multitude of Plesk/cPanel/Wordpress hosts, which are fine in so far as it goes, but not useful to us).
That's not to say we don't have some good hosts - Mythic Beasts jump to mind. But they're often smaller firms without the scales or hardware choice/availability and it's often a case of requesting quotes, etc on a build-your-own basis, which often end up expensive if you're asking for ones or twos (not speccing out a whole rack of kit, when you've reached the point where the TCO has shifted in favour of ownership and colo vs. renting).
