From what I've read on the Autodesk website concerning Fusion;

Eligibility for free use of Fusion is for Individuals with non-commercial personal design projects and/or individuals doing home-based non-commercial manufacturing and fabrication. Also, hobby businesses that generate in excess of $1,000 per year are excluded. For those that are eligible for personal use can access all the "core" design and manufacturing capabilities. I presume that reference to "core" elements means those capabilities that everyone has had access to up to this point. I'd be interested in hearing from anyone who may have a different take on this.

I was particularly concerned with what I've perceived to be a change of terms of service as I have predicated a primary retirement activity on doing CNC work. My use of Fusion is going to be an important part of that.
