I thought carnivores don’t even consider tea, just allows coffee because too many are addicted to it 
Well if you ask me…
I couldn’t care less about what part I eat and what is it, my body is fine with both, both substances are just for joy as they don’t do anything noticeable to me (except maybe the subtle help of coffee to output processes
I don’t need that but I can imagine it being helpful)…
But I drink tea now because I hate being addicted to anything and coffee managed that (besides, it costs money while not giving me anything good and it takes away time). Even carnivore did nothing to it. I stopped eating the other problematic items, never missing them… But not coffee.
Anyway, it’s funnier to belong to the minority
Not like I am a carnivore but I am trying to stay very close…
If you catch me in some moments and ask tea or coffee, I say cocoa. But that’s farther from carnivore. Still a lovely thing… I consume it in some desperate times when I try to stay away from coffee, no matter what as it is a great (and only) substitution of it for me. But I am very much aware about its non-carnivoreness and carbs.
Tea is sweet, if it will bother me, I probably will stop or choose the kind that isn’t sweet.
Coffee has no such problem, no matter how weak and non-bitter ones I have. Or currently not have. It’s No Coffee Day #4 today! I think. I am bad with time.
For others… I suppose everyone should choose whatever, I usually chose both and I am not even among the ones who desperately want something non-water to drink (I want my other drinks but not as desperately as some others). My coffee and tea are subtly flavored waters, I prefer both super weak 
@PaulL’s medication reasoning makes sense. I don’t have this excuse
I just like the taste sometimes. But I need something with it. And that often went in the way of my fasting.
But as I am merely stay close to carnivore most of the time, I embrace plants anyway. In very tiny amounts and only when pretty much needed or gives me a too big deal: great joy and variety for no harm at all. I need little condiments but they come handy. And sometimes I go a tad farther, it’s still very little and I can handle it but it’s not carnivore.
So no wonder I don’t see why I would stop drinking tea 
Carnivores who ONLY eat meat, well they obviously think differently about tea and coffee.
And the not super strict carnivores are in-between, it depends. Some people don’t like coffee, some people have problems with tea or coffee…
I don’t see why to restrict people if they handle the substances well.
But it’s just me, a not-even-carnivore who can handle all edible things pretty well. The sugary ones less well though.
