My guess.
Finex whales reducing shorts push Market Makers to buy bitcoin on cheaper exchanges (using #tether
because other pairs have basically no liquidity 
) and sell it on Finex (where price is higher due to the short closing).https://twitter.com/jon_ftx/status/1408903828339056644 …

So is this a collaboration between Finex whales and market makers on an arbitrage trade?
Not a collaboration but just how markets work in general. Finex whales build / reduce positions. Market makers provide liquidity for that.
