Not popular? By who's standards? You're entitled to your opinion, obviously, but that's all it is - an opinion. I've seen numerous Elachi ships since the lockbox was released and own the Escort myself. Okay, perhaps it isn't THE most popular lockbox ship, but it's definitely popular enough that lots of players are using it.
Because you like something doesn't mean it's popular. I happen to like the way the escort looks, too. I have one myself. That doesn't make it popular.
You can tell it's not very popular by the amount (or in this case, lack of) announcement spam from people opening boxes and winning them. You can also judge its popularity by it's price. It took just a few days for the Elachi ship to drop under 70m on the exchange. Compare that with the talshiar box, which stayed over 100m for over a week.
And that's with many more talshiar boxes being opened. As someone else pointed out, if it was really popular they wouldn't need to do the video.
I just think the video's a lost cause, the box is underwhelming overall. Their time would be better served making the next box better or (perish the thought) creating new content, fixing bugs, and generally improving the game.
