does burning man still take a 10% commission on honoraria art?

There’s an artist agreement from 2014 on their website that states the following.

Is it still true that a condition of accepting honoraria funding is guaranteeing that you'll profit share with the organization?

Sale of Artwork

Burning Man funds its support for the arts from a variety of sources, including ticketing, grants, fundraising, and art sales. In the past, if a piece of funded art was sold, art agreements assessed a fee of up to 10% of the gross sale price – but not more than the amount of its honorarium payments – to help fund more art in subsequent years. For 2015, this contractual fee has been reduced; it will be capped at 10% of the net sale proceeds, after deducting other commissions or debts that an artist owes on the work at the time of sale, and still not more than the honorarium payments. The fee is now also limited to sales within a period of 15 years after the artwork’s exhibition in Black Rock City.
