It has nothing to do with the way it was manufactured; rather, it was
*installed* upside down.

There is only one conduit, or clamp opening at the bottom of these
molded outlets.

There are *no* openings at the bottom. The single opening is at the top. Yours
is mounted with the top down.

Mounting it upside down would require the feed coming
in from the top, which means putting 90's on the conduit.

Yours already is mounted upside down. Mounting it _right side up_ would
require the feed coming in from the top.

My cable comes from the bottom.

Hence the outlet is installed upside down.

Of course for applications where the feed comes from the top, then its
not a problem.

That's what they're designed for.
