ULAs have a nice feature that GUAs don't: your stack won't choose a ULA as a source when the destination is a GUA.   If they get a GUA from RIPE, they lose that feature.

If they get GUA from RIPE, they don’t need that feature, as there aren’t multiple source addresses to choose from.

You’re not making much sense here, Ted.
