if you mean support as in ‘provide help for’ you’re probably right. google’s help for the existing free Apps is pretty non-existent.

If you mean support as in ‘make G+ available to’ – I’d bet you’re wrong. People with their own domain and the free google apps (like me and your readership)are the IT evangelists who would push friends, employers and clients to adopt G+. Lock us out and they’re losing early adopters who will have a huge influence on whether this floats or sinks.
