Is this even still possible? Since EIP-1559 miners like ethermine stopped including their own tx for 'free' presumably because you cant pick and choose anymore.
You can still pick and choose, EIP-1559 forces miners to burn part of the fee, which means it's no longer "free" to the miner to include these transactions. In the case of this transaction, Bitfinex also included a very large tip that went to the miner.
