To beat Google and Purism, it would be nice to offer to use our own domain on your services.
Correct me if I’m wrong, but the back end for the /e/ OS Apps is “just” a nextcloud instance which should mean you can easily swap it out for your own nextcloud instance. Is that what you mean?
/e/ Cloud is not “just” a NextCloud instance.
It also comes with a full email system, that makes all the difference when it comes to DNS domains 
@Scytale of course I could easily reBuild those services with MailCow and Cloudron, just to give 2 examples. But I thought I could be easy money and open the services to a new categories of persons (entrepreneurs, small business, …) which basically only have the choice between Office 365 or Google Workspace. I guest I’ll build my own business and target this market.
