They are not Myanmar citizens, Myanmar already has a sizable Moslem population that is well-integrated into the culture, everyone hangs out together, and gets along, regardless of religion.
If you stay in Myamar long enough, you will hear the story that the top Maynmar officials are being bribed to take the Rohinga by wealthy Moslem countries with plenty of oil money, who want to flip Myanmar to being a Moslem country.
I don't think there is anyone who can argue that bribery is not out of control in Myanmar, and that there is little the people can do about it.
