Well, it looks like they reversed the STEP export restriction: https://www.autodesk.com/products/fusion-360/blog/changes-to-fusion-360-for-personal-use/ so it is still usable in the short term.

But i agree with everyone, there is no free lunch, especially with Autodesk, and I wouldnt continue depending on it , if it had been part of my workflow.
