Installing the non-free firmware on Debian is as easy or easier than similar installation on all other operating systems. So this is really a complaint about something that is almost as easy as it gets needing to be just slightly easier. It’s making a mountain out of a molehill.

That said, who cares if some users want it? Debian doesn’t aim to serve all users’ needs. Those who want non-free firmware bundled with the operating system can get that with one of the many Linux-based (or non Linux-based) operating systems out there. Debian just isn’t for those users. That’s fine.
