In addition to what I wrote previously (that I think they differentiate between the current government and the State as a whole), I think that in some cases, the government was okay with or even supported the settlements originally and considered it good for the country. The settlers were considered to be putting their lives at risk for the defense of the country and then felt betrayed when the government evacuated.
I’m not 100% sure of this though, although I do think it was the case. There may be people here who know more about it.
