I did a quick check on this; something was tugging at my memory.

Although “plantation” definitely has the meaning you refer to in the present and for some time past, its older meaning is “a colony or new settlement.” So to cut a little slack for Rhode Island, the”plantation” in Rhode Island’s name probably has a more positive meaning than you might think.
