You called it! Today I got an email from them saying:

5 Nodes Free is now 3 Nodes Free
As an existing 5 Nodes Free license holder, nothing changes for you!
All existing 5 Nodes Free licenses will remain 5 Nodes, including at renewal.
At renewal, the license issuance will change from 3 years to 1 year, with the ability to renew each subsequent year.
5 Nodes Free remains “Free” as long as 5 Nodes or below are used.
If you need more than 5 Nodes, purchase a Home and Student, Professional, or Enterprise license.

Same. Feels like it's broken when not even the community creator posted a "hello world '.
