Because Tramp has been instructed so? I suppose, following the above
link results in

(insert-file-contents "/me-oHC15RC7JGTNLxjTenLetw@public.gmane.org:papers/c=
urrent.pdf")

This is remote file name syntax, and Tramp tries to do its job, using
the default method "plink". You could avoid Tramp's reaction by a link
like (untested)

[[file:/:/me-oHC15RC7JGTNLxjTenLetw@public.gmane.org:papers/current.pdf][pa=
per]]

Alternatively, you could choose another file name.
