Who is selling them BTC for USDT apart from a few daytraders? Where is the sink of 2.8 billion USDT?

That's a very interesting and plausible hypothesis.
One wonders whether the prolonged slump might lead to some sort of bursting of outfits like Tether/Bitfinex. It seems like a downward spiral of people selling BTC and Bitfinex doing the dance you described, and a bigger hole being created.

The other allegation (which is pretty viable) was with large reserves to play with, they could cause crashes or spikes in order to gobble up their users risky shorts. Shorts they would know the exact number and values of.
So they issue 11million unbacked USDT and use it to buy bitcoin. They sell the bitcoin for 10million USD on one of the exchanges that allows bitcoin to hard currency exchange. The 10% loss is because you have to pay a premium to exchange bitcoin to real currency. Bitfinex then pays the 10million USD to the customer in exchange for the 10million USDT which is retired.
The net results are 1million new unbacked USDT have been printed, and the illusion that USDT is backed by USD has been maintained.
Possibly the "Bitfinex issues unbacked USDT to buy bitcoin" step is being done not based purely on customer demand, but on a periodic basis when bitcoin price is falling.
Maybe Bitfinex has a hope to preserve their fraud by propping up bitcoin, or to dig out from under the fraud by building a big long bitcoin position and hoping it will rise in value.
Or maybe the timing of USDT issues with market drops is just that bitcoin price falls when there are more sellers than buyers, which is the same time there are more USDT redemptions. So to carry out the mechanics above, Bitfinex has to print tether to fund the redemptions at the time of the drops.
