The 6% fee (more normally 5% around these parts, western US) is paid by the sellers, but with the buyer's money. Usually. However, it's important to note that there was never a requirement for anyone to pay anything; it was simply what was commonly put into contracts. The settlement didn't change anything about that in particular.
I just sold a house a couple weeks ago. I agreed to pay my seller's agent 2.5% out of the sale price. I also, in the contract, offered to pay 2.5% to the buyer's agent. In the event that my seller's agent was also the buyer's agent, that 2.5% would be refunded to me. What actually ended up happening was that in the offer that we ended up accepting, the buyer asked us to pay 3% instead of 2.5% to their agent. We agreed.
