Patrick in Palm Springs recently told me that:
Palm Springs has two Boards of Realtors (CDAR and PSRAR) in the Coachella Valley (Palm Springs, Palm Desert, Rancho Mirage, Cathedral City, Indian Wells, La Quinta, Indio, etc.). CDAR has sent an email to their brokers stating they will require all photographers to sign an agreement assigning all rights to them. This is for all past shoots as well as future shoots.
There have been other attempts like this in other geographic areas for a number of years. Here is one example we discussed.
This approach by MLSs, Realtor organizations, and brokers arise for several reasons:
The rights of everyone involved must be considered. One solution to this issue that Joel Rothman has advocated for is to form a real estate photographers association. This post from 2016 by Joel where he makes the argument for an association of real estate photographers.
Primarily because of Joel's leadership in this area, a real estate photographers' association is well on its way to being formed but it is not yet complete.
So for these kinds of situations like this one in the Palm Springs area, photographers who are in favor of defending their photo rights need to make themselves heard by the local Realtor board and explain that photographers rights must be considered along with Realtors and MLS rights. That can be done but frequently, it takes the education of everyone involved. This is the ultimate goal of the upcoming real estate photographers association.
