Would we also need to carve out an exception for the typically vapid
&quot;announcement&quot; articles advertising paywalled academic journal papers?<p>The announcement-mills (phys.org comes to mind but there are plenty of
others including nature.com itself) are not really &quot;original&quot; sources, the papers are,
but such announcement-advertisement articles are submitted regularly.<p>Finding the freely available pre-print and&#x2F;or author provided copies
without resorting to (ahem) <i>other</i> workarounds is a pain but useful.
