Is the player abusing their feature or am I being pedantic?
Don't do this.
The player isn't abusing anything. That is exactly what the ability does. If it's night, or in a dark enclosed space, whether that's a dungeon, castle, inn, whatever, they can teleport.
This issue of it going from a cool thing to a button to mash is why I think it should have been character's speed, with a feature that increases speed in darkness, and spend 1ki to double the distance of a single teleport or to ignore the darkness restriction. EDIT: and I would have had the attack bonus come in later. it would be too much for an always on ability.
Anyway, the balance of the feature does assume that not all rooms/areas will have areas of dim light or darkness. That's important to remember, and much simpler than any heavy handed "consequence" for using one of the main abilities of the character's subclass. Dude presumably took the option, in part, to be able to teleport in darkness. It isn't limited per rest or the like because it doesn't need to be. if anything, it would only make sense to make it cost KI, and if you do I recommend making it use movement instead of a bonus action.
Well, when you think about it, night is nothing but the shadow of the earth. And darkness in a dungeon is the shadow of the ceiling. As long as there's light somewhere in the universe, all darkness is just the shadow of whatever's between you and the light.I guess I was wondering about shadows when there is not light. Is it considered shadow or is it just dark? I mean we don't call night time shadow time... would shadow step also function at night? I guess it would...
I have no problem with this and would totally allow it.

If it stops being cool if the character conatantly teleports in darkness all the time, limit it. Don't limit it in any combat situation. It is at-will. But blink around for 12 hours straight? That is not what it is for. 5 min? of course why not.
I would also not let a wizard fireblast for 12 hours every 6 seconds or let the fighter swing his axe for 12 hours every 6 seconds. Has nothing to do with punishing someone. Everything you do is exhausting if you don't take breaks and it is reasonable to tell your player that you won't allow him to shadow step all day.
