Workstation Pro 17.5.2 is now free for non-commercial use. There are no restrictions - other than you are obligated to purchase a subscription/license if you're using Workstation for commercial purposes.
Broadcom has changed the game. If you're using the desktop virtualization products for personal (non-commercial) use, you can use the "Pro" editions for free. I suspect you'll be able to download future versions under the same free terms (unless Broadcom changes their minds again). But, the option to purchase a perpetual license without support is gone for commercial use. You're now required to buy a subscription (which includes new major versions and support) if you're using Fusion or Workstation for commercial purposes.
