Hey there.
What you're actually seeing is the tail end of a dispute between two individuals, the owner of Nakamal @ Home and the director of the now closed "True Kava Labs". True kava labs is no longer in the kava industry.
N@H labels it distinctly as non-noble, which is truthfully all we ask for. So technically we don't necessarily have a problem with him carrying it. The issue I feel is that when he does carry a tudei kava, it will inevitably invite questions regarding his other kavas as well. Obviously they're not tudei, but to a newbie that sees the word, it may just produce further questions.
Be that as it may, once that's out of stock it will be no longer available. So this feud is almost over, and we can stop answering questions like "Why does this kava have a guy playing a trumpet on it?", lol.
TL/DR: Bad blood.
