Why, exactly, is it more ethical (or even not unethical at all) to force
another into parenting a child than to force another not to have a child?

The deception that would be involved in forcing someone into parenting
another child against their wishes is what makes that more unethical.

And I would dispute the suggestion that there's force involved in
declining to have another child; there may be a breakup of the
relationship in order to get that additional child (or children), but
the partner who doesn't want the additional child doesn't get to force
the partner who does to stay in the relationship.
