The fund is closed off to outsiders, so the fees are don't matter in the same way they do for most funds. In the podcast episode on Rentec done by Acquired, the hosts speculated that rentec kept the high fees as a way to ensure they have enough to handsomely pay less tenured employees who don't yet have much money in the fund.
I'd heard that the Medallion fund was closed off, so I wasn't really sure of the reasoning behind that continuing fee structure, but that line of speculation does make some sense.
