To be fair casting for both Tilda Swinton as The Ancient One and Johnny Depps as Tonto were both criticized when the movies were released. Probably not to the level Halle Baileys casting was, or by the same people, but both were definitely seen as whitewashing.

Its also likely The Ancient Ones casting got as much attention as it did due to the political nature of the change (seen as to appease China over its history regarding Tibet).
