Quite a few environmental groups have explicitly expressed support for the Tesla plant, as they see it as a net win for the environment. Those groups which are protesting seem to have very one sided view. They oppose any change of state, even if the trees that Tesla did cut down for the buildings were scheduled to be cut down for wood in a few years anyway. And Tesla financed planting of new, more varied trees in other areas. And some groups definitely are just pretending to be environmental while driving a political agenda.
