What Happened to Flynn.io? (and Others)

Many of the PaaS open source implementations whether built on top of k8s or otherwise turning up dead or getting lower and lower traction. Examples would be flynn.io, for example or draft (https://github.com/Azure/draft) seems also sort of dead. What gives? What's happening? Is there no place for PaaS anymore because there are too many already? Or k8s deployment and operation is that simplified to the point that with Helm, Tekton and Brigade etc - there's a general convergence on a DIY K8s and away from PaaS layers even if they're built atop K8s?
