You are right but it's likely most people wasted a few minutes reading about it before discovering this?
This is like the B2B SaaS marketspace - it's almost taken for granted that your app integrates with Salesforce. People are surprised if it isn't.
However, anyone who runs, Microsoft CRM, SugarCRM, Netsuite, etc. - are all used to hearing "Sorry, we don't integrate with X". I'd say ubuntu falls into a similar category....
