Here's the deal with the third person cam.
Originally we were never meant to have any form of third person view, by design. Maintaining continuity of the first person experience or whatever.
Anyway, people obviously didn't like that because they wanted to look at their ships, and frontier eventually decided to capitulate when they realised it would boost paintjob sales and provide a lot more free publicity from screenshots and videos. Funny how profit will light a fire under one's creative integrity huh.
Well, people still want their immersion and for things to make sense in-universe, so many suggestions were thrown about for how to reconcile the two ideals.
Frontier hummed and hawed a bit but eventually we all kind of agreed on some sort of follow-me camera drone that you could launch and have track your ship for those cool exterior shots. The concept sounded pretty sweet, being able to control it directly or give it preset commands for those star trek flyby shots or what have you.
Now something like that takes a while to implement, you need art assets made, code needs to be written, QA passes, feedback stages and all that usual malarkey.
Frontier didn't know when that would be able to happen though, given that this was still early after launch and a lot of work was being done for the season 1 patches and horizons ticking away in the background taking up all of their time and effort.
But one thing they already had lying around was the debug cam, which was a very basic system that functioned off the ship's existing control settings and simply moved the "head" camera we normally see through from inside the cockpit. This only existed so the devs could make those cinematic trailers, but in order to tide us over while we waited for the real external camera system to be developed, they added some range limits to the debug cam and gave us access to it.
You can probably guess where the problem is arising now.
2 years later and the proper camera system hasn't been so much as mentioned ever since, and as far as most of today's playerbase is concerned, they're either too new to know about this or it just fell down the memory hole.
So if you want them to cut the cord, just remind them of what they originally promised, and refresh everyone else's memory of the same.
