That doesn't seem to be the case for long-tail VPS providers. It doesn't seem to really be the case for the big cloud providers, either, as most of what they offer is fairly commoditized -- I've been using GCP for years to host Kubernetes clusters, Postgres databases, Redis instances, standard Linux VMs, etc., and while there'd be a cost associated with migrating out of GCP, I don't feel locked into it in any way, as the tools I'm using there are the same tools I'd be using regardless of where they were hosted. The market for IaaS and for SaaS are very different from each other, and the walled-garden approach doesn't seem to have significant traction in the IaaS world, thankfully.
