Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Among my colleagues at work and friends, there are not so many who are using family domains. I asked some of them and they say they do not care and that is important only if you are a business. They see it more of the show-off, hobby, nerd, enthusiast thing. But lets exaggerate and say that 10% of all home users do. Now compare that to the amount of business customers. MS does not even bother.
That's wrong, imho. My family uses the same email addresses since 15 years. The providers have changed a couple of times since then, our addresses stayed the same. I do not want to stick with a provider, only because I then would have to choose a new email address.
And yes, I am willing to pay some extra money for custom domain support, although it is not a big thing for Microsoft to offer it free of charge. But I am certainly not willing to pay 600€ instead of 60€ per year for private use. So it is up to Microsoft to distinguish those two offers more.
Best regards
