Requested change
Change the "Important" note information in the 6.1. Node configuration management with machine config pools section (OCP Architecture Guide) to avoid referring to legal terms of subscription usage. The official product documentation should avoid making references to whether a customer is or is not legally required to pay for a subscription, or how to configure the product to "avoid" paying for the subscription.  

The note in question states the following:
Important
Any node labeled with the infra role that is only running infra workloads is not counted toward the total number of subscriptions. The MCP managing an infra node is mutually exclusive from how the cluster determines subscription charges; tagging a node with the appropriate infra role and using taints to prevent user workloads from being scheduled on that node are the only requirements for avoiding subscription charges for infra workloads.

A suggested rewording is to state that the suggested configuration will ensure "the most accurate subscription usage data/tracking" for the product. The following is one example of rewording this text:
... tagging a node with the appropriate infra role and using taints to prevent user workloads from being scheduled on that node can be used to generate the most accurate subscriptions usage data for infra nodes and workloads.

Red Hat Supplementary Style Guide rule
Legal > Cost references (excerpted)
Avoid all references to the costs and charges of Red Hat products .... because they can confuse users and cause legal concerns.

Background
Due to a comment in the Slack #forum-subscriptions channel, the SMX docs team was made aware of this text in the OCP Architecture Guide. It is unknown how frequently this topic/info is reused in other OpenShift guides, and across how many different versions this information appears.
