As someone who's stage-managed the migration of significant IT assets out of at least the big 3 providers who "controlled the compute and storage infrastructure" (AWS, GCP, Azure), I'm curious if your faith in 'competition' as a control is naïve or deliberate obfuscation (boy have I seen both). There are things you 'can' do, because yes an alternative, in theory exists, and there are things that are practical to do.
