^Maxson turned it into a xenophobic, technology fearing, military group that tries to force the locals to support them. Or at least his chapter. Makes it unlikable or makes it harder for me to like them in general than the previous versions. If we ever see Sentient Deathclaws again, we have to protect them from Maxson. Seeing as it was a creation of man, and likely an intelligent deathclaw would onyl further his reasoning that they are to dangerous to be allowed to live. Well, actually I just remembered there is a somewhat more intelligent deathclaw when you return her egg, she doesn't attack outright, she just minds her own business and thats that. Less feral on the attack mode. But not a high intelligence like Fallout 2.
Hopefully IF(most likely) the BoS return in Fallout 5, they are more about preservation of tech and keeping it out of the hands of thosr who might abuse it, instead of hating everything not human, using intimidation tactics on locals to get food, and not xenophobic to the extent Maxson made his preaching the destruction of people or a group of people they disagree with in ideals.
