I'd wager at least 95% of Comcast's users aren't network engineers,
security bros, or in some technically competent field.
If you were building a system to support hundreds of thousands or millions
of users who couldn't distinguish between a DVD drive and a cup holder, how
would you make it easy for your front-line support staff to help them use
the service they paid for?  Want to walk them through factory resetting an
old WTR54, hardwire a computer/laptop to it (if they have one), sign in
with default creds and then properly configure wireless?

I'd rather say "What do you want your wireless network name to be?"  "Ok,
and what do you want your password to be?"  "Done.  Try connecting now."

In any sort of business environment you should be briding the modem and
putting your own firewall in.
