When installing an operator, OLM creates an "operator" Custom Resource whose status will be updated to contain a list of resources associated with the operator. This is done by labeling each resource associated with an operator with a label based off this code: https://github.com/operator-framework/operator-lifecycle-manager/blob/7eccf5342199b88f4657b6c996d4e66d9fa978fa/pkg/controller/operators/decorators/operator.go#L92-L105

Always

1. Create a subscription named managed-node-metadata-operator in the openshift-managed-node-metadata-operator namespace, which causes the truncated label to end on `-`, which is an illegal character.
2. Watch the OLM Operator logs.

The adoption controller within OLM continuously fails to adopt the subscription due to an illegal label value:

The adoption control creates a label that can be applied to the subscription so it may be "adopted" by the controller.

This was orginially fixed in 4.11 here: https://github.com/operator-framework/operator-lifecycle-manager/pull/2731
