Okay, cool down and let me explain a bit π
That's because those templates are not part of Xen Orchestra software itself, because those VM templates are things we build and assemble on our part, then upload to our own servers, hosted for people registered with the virtual appliance (XOA). So using XO from the sources is not losing any XO features because XOA hub templates aren't part of it π€· This is extra stuff outside XO scope, that we give for free for our XOA users (yes, XOA Free users). So we do not get any money for this.
It's just operating systems pre-configured with Cloudinit installed (or sometimes not). Again, it's not part of XO itself, and nothing prevent you to build your own templates, ready with Cloudinit.
I hope it's more clear now.
