Claim LD11-HQ-C08 (v1.0)

The UK CMA found AWS and Microsoft hold significant market power in UK cloud and identified egress fees, interoperability barriers and Microsoft software licensing as constraints on switching and multi-cloud.

Research opportunities this claim motivates

What this claim leaves open for research. Each is a hypothesis about a gap, not a finding.

Did UK public bodies switch cloud providers after egress fees were waived?The CMA identified egress fees, interoperability barriers and Microsoft licensing as constraints on switching; the claim does not license "solved switching", and measured post-action switching is named as what would change it.
Do AI startups backed by a cloud giant end up running on that giant's cloud?The CMA found switching constraints in cloud generally, but the claim explicitly does not license AI-specific foreclosure; that is the gap being measured.
