What is this, Deadpool?
The crew of Trek knows they're finding loop holes due to the writing staff?
Are we arguing Trek Universe facts or real world writer facts because I've lost track?
You asked about the loopholes and I gave you the answer. I'm not breaking the 4th wall, here.
As a producer, one of my main priorities is to my audience. They are what draws in sponsors to create revenue for my show. The Borg, like Venom and Doomsday proved to drawn in viewers/readers/money. TV is a business just like any other. So if my audience is telling me they really like the Borg, Venom & Doomsday by increased sales/viewership, then it's incompetence on my part for not filling the supply of that demand.
The Borg are fan favorites.
Every time they showed up, viewership increased.
Voyager was a show that needed to keep up it's ratings, so as a writer/producer you do what is best to keep the show on the air. If that means showing the Borg every season to get folks to watch, you do it. If the fans don't like it in hindsight, it's too late. While the show was on, feed back for the Borg was positive.
And, as a result, the producers/writers creation fall heavily out of fan favor. Gee, I wonder why? No one trashes the Klingons or the Romulans. No on trashes the Green Goblin. And no one trashed Lex Luthor, until, you guessed it, the producers/writers (i.e., you) decided to overuse/misuse him.
The Klingons are fan favorites, but you never saw them suddenly becoming logical. They never started becoming calm. They never inexplicably started to say, "Today would be a good day to die, if it wasn't Sunday." And they never decloaked a space station that was 1-light year from Earth.
The reason the ratings kept jumping, is because people kept coming back to see if the writers were actually going to write a good Borg episode. I know, because that's why I kept watching.
I was the obsessed Borg fan at one point. I had almost all Borg paraphernalia, right down to that Borg bank that had a tractor beam on the Enterprise D all the way to a mini borg cube paperweight. So, of course, feedback for the Borg themselves was positive. I AM the audience the producers were catering to and as that audience I am telling you
the producers screwed up. I came back, because I was hoping for a better story. I was hoping they would be redeemed. I was hoping for an origin story. All I got was increasingly weak Borg with terrible Borg Queen portrayals. (At 1 point the Borg queen is shown treating her drones as if they were common thugs, instead of treating them as an extension of herself, you know, like the Borg are supposed to be.) But they were Borg and Borg were exciting, like that very good lover who cheats on you, you keep coming back for more, because that loving is soooooo good. But the "aftertaste" is terrible and the regret is huge.
Stick to the rules that I mentioned before and you'll be fine. You want to show the Borg every season? Fine. But people have to die. Significant property has to be destroyed and not rebuilt in the very next episode (I'm looking at you Delta Flyer). Tears must be shed.
Just because something is popular, doesn't mean you abuse it. A good writer knows this.
