It would be better to post the original Bloomberg article, rather than the Cointelegraph one.
https://www.bloomberg.com/news/articles/2018-08-24/not-even-515-million-in-new-tether-can-help-this-crypto-dump?srnd=cryptocurriencesEveryone should read Kraken's article disproving the news media's clickbait and the scientific paper FUD that USDT is printed to manipulate bitcoin.
In any case, I have already told everyone. USDT is issued when the price of bitcoin falls because there is more demand for USDT. Also when there is more demand for USDT, there should be more supply to maintain the $1.00 peg.
I agree with you that is how the peg should be maintained in the ideal case. New USDT should be issued in exchange for dollars, and the dollars should be held safely by the Company issuing the USDT. It is the latter part of the equation that people are not certain about.
