Until now I'm a happy user of the community (free) edition of Genius Vision. 
The system is running in a non profit museum with only a small budget. 
I'm busy installing new hardware and wanted to download the latest version. 
But now you have to be a Patreon member and pay a monthly fee (minimum one Month) for downloading  a copy    
Why   
I have no problems paying a small amount for a copy but I like to use Paypal etc.  
  
Luckily I have a copy of the installer but for future updates I have to do something with Patrons
