In GNU Emacs 28.0.50 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.30, cairo version 1.17.4)
of 2021-09-20 built on lilydjwg
Repository revision: 3c513435369826e44a53dcb12ecc14657e03c73d
Repository branch: master
Windowing system distributor 'The X.Org Foundation', version 11.0.12013000
System Description: Arch Linux
It can be reproduced in emacs -Q using the following snippet.
#+begin_src elisp
(setq newsticker-retrieval-method 'extern)
(setq newsticker-url-list-defaults nil)
(setq newsticker-url-list '(("Planet Emacslife" "https://planet.emacslife.com/atom.xml")
("LWN (Linux Weekly News)" "https://lwn.net/headlines/rss")))
(newsticker-show-news)
#+end_src
Then press G to fetch all feeds in LWN and Emacs planet, but nothing is
displayed in the right window.
newsticker uses
wget -q -O - https://planet.emacslife.com/atom.xml
under the hood, and wget exits with 0. All observed by `bcc execsnoop'
and `bcc exitsnoop'.

I don't use Newsticker, so I don't know what it usually looks like, but
following your recipe I get the following display:
[-- Attachment #2: Type: image/png, Size: 123990 bytes --]
[-- Attachment #3: Type: text/plain, Size: 228 bytes --]
Which certainly isn't empty. So I'm unable to reproduce the problem.
Are any further steps necessary to observe the bug?

After revisiting the output content by wget, I found that's a wget bug.
https://lists.gnu.org/archive/html/bug-wget/2021-09/msg00010.html
wget prints "SSL_INIT" even in quiet mode (-q), so that newsticker
failed to parse.
Sorry to bother you, silly me.
