Well, let's see how you get to the first of these two pages (call it
A) from Debian's home page. The first principal paragraph on the home
page starts:

        "Getting Started

"If you'd like to start using Debian, you can easily obtain a copy,
and then follow the installation instructions to install it."

What's more natural than to click on "obtain a copy".
Then you see "Download an installation image" and click on that,
to arrive at:

https://www.debian.org/distrib/netinst

In contrast, to get to the other page (B), you have to read through
the menu options (in fine print), and _not_ click on "Network Install"
(which would take you straight to A), but choose the next item,
"CD/USB ISO images". When hovering over that link, the sight of
"https://www.debian.org/CD/"; might cause people to avoid it
because they don't want to burn a CD.

Shame about the heading, no mention of USB images. Now scroll down
that page, and avoid clicking on the "network install" link (although
that might be your aim). Keep going to the paragraph headed CDs, with
the architecture links. No mention of USB here.

That's right. Page B is a better route to take, but the links to it
are less prominent, and less clearly labelled for someone who wants to
install over the net rather than burn or purchase CDs.

But irrespective of that, it would be sensible to make it as easy to
get from page A to http://cdimage.debian.org/debian-cd/current/i386/iso-cd/
without any right clicking or rubbing out, in the event that you get
drawn down this path. Whether that's a small proportion of people or a
large one seems irrelevant.

Go back one page to https://www.debian.org/CD/http-ftp/ and
read the first paragraph. The one that's boxed, shaded and
has a lightbulb to draw attention to it:

"Please do not download CD or DVD images with your web browser the way
you download other files! The reason is that if your download aborts,
most browsers do not allow you to resume from the point where it failed."

Relatively it is, if you have been seduced down the path to page A.

A reasonable test is "Can I email it? No? Then it's huge". And there's
no warning by the link of its size.

A lot of people who need firmware are likely to download the other
one first, so you can double its size on that score.
