From a variety of diffuse bits of evidence (maybe I’ll write a book someday…maybe. I will be terse here.), it seems to me that the ISU is not especially interested in supporting potential figure skaters from countries lacking (imagined) majority white or Asian populations.
They're not much interested in supporting potential figure skaters (or speedskaters) -- their mission is to support actual skaters, on an international, not a local level. If a country where figure skating had never existed in the past -- where skatable ice had never existed in the past -- wants to develop a figure skating or speedskating program, the ISU can provide them a path to membership and assistance with developing their programs, but they can't create a program out of nothing from the top down.

See especially Articles 3 and 4.

For singles skating, you might be interested in the
ISU World Development Trophy events held this spring in
Poland (included skaters from Morocco) and the Philippines (no direct link but it took place April 10-16 in Manila; if you search the ISU events calendar you can find links to the announcement and protocol, and if you google ISU Development Trophy Manila you'll find links to quite a few of the performances on youtube.
There's also a thread here at Golden Skate about these events
This is new this year, and hopefully there will be more such efforts in the future. But again, these are ways to welcome developing figure skating programs into the ISU and provide opportunities for international competition below the JGP level. The ISU can't create the new programs and new skaters themselves.
The cultural points you raise have some merit, but more as an acknowledgment that individuals have cultural biases, and an organization that is primarily composed of Europeans and North Americans of European ancestry will skew in its preferences in favor of those cultures. As more federations from other parts of the world join the ISU and send skaters and officials to its events, the weight of those preferences will be diluted through new points of view. But it will take time.
