I don't think I noticed one very important thing in this discussion regarding Homeward, that by moving the Boraal to another planet they could be dooming the Boraal to disease that they have no means of fighting. They are also introducing what may well be an apex predator onto a planet that would have developed it's own advanced species. Or the Boraal could introduce a disease that would kill on the scale of the Permian Extinction. You could say that the transporters would filter out any disease, except that it doesn't filter out all micro-organism that can cause disease. For example in our gut are bacterium that are beneficial to humans, in fact needed by humans, but can cause another species, even other humans to become sick. So the transporter would leave those in the Boraal because the Boraal need them. Those micro-organisms could then infect the planet to which they were moved. Moving them was a stupid thing to do, to quote Jurassic park: The Boraal were selected for extinction. The choices were moving the Boraal to another planet. Possibly dooming the planet and/or the Boraal. Leaving them to their doom. Bring them on the Enterprise, destroying their culture. Why? Because to them only gods can travel to the stars, make water out of nothing, and moving from one place to another without walking there. You can't get around that. Send an Aircraft carrier back to when humans were hunter gatherers over even when we became farmers. Would those primitive humans understand a machine gun? A jet fighter? or a huge ship that travels the waters faster than they can run on land? Yes, it's cruel; but in this case leaving the Boraal to their fate was the correct choice.
