Well as someone who's actually used them as a customer, OpenStack hosting providers do give more functionality than DO, Hetzner, etc, plus they have an open API. None of them compete with the "big 4" public clouds (everyone forgets Oracle is still around...) but if all you want is IaaS then you don't need them.
I know OpenStack is a tire fire to maintain, I've worked with it for large-scale on-prem data solutions. But if a company wants to kill themselves to maintain it for me, I'm happy to pay for the privilege.
Being a customer of an OpenStack provider isn't exactly a picnic. I could show you a long stack of support tickets from all of the things constantly going wrong.
Given a long list of support tickets vs Effectively relying on responsible stewardship by Musk and the King of America, I suspect there will be many a developer who find the long list of ticketed issues to be the less hard problem to tackle.
There are sadly a lot of "sky is falling" type people out there yes. This is why we have to determine a threat model before we implement a security response...
But that's also the point of my other comment in the thread -- a French company builds basically all of the physical infrastructure that datacenters run on. This attitude can be applied both ways.
