How's the Enclave any different than the BoS hoarding technology?
The Enclave make their own.
They don't scavenge it like common raiders or prospectors.
The BoS has their reasons: they want to salvage it for the future in order to make a future for everyone
I think you better check their mission statement again.
The actual ideals of the BOS state nothing about giving that technology back to the people, indeed they don't think those people are worthy of handling it.
the main Brotherhood is strongly paranoid, and not only seeks to preserve technology but actively remove it from outsiders, is disinterested in nonmilitary assets, and engages in little if any work to actually improve their tech.The eastern and most likely midwest BoS is much more successful than the NCR, at least formed together.
Fallout 3 Scribe Rothchild:
"The Midwest BOS has fallen on hard times." (paraphrasing)
First and Foremost though, neither the CWBOS or the MWBOS are truly "BOS" in the sense that they were both cut off from the elders in the west (forcibly, the MWBOS was sent west to get rid of them).
Secondly, even then the NCR has much more resources at this point than every BOS chapter combined with a population of 700,000 to boot.
The Enclave has more tech and resources and still manages to lose each time they try to do something.
For reasons that either
1. include the player character killing them off
or
2. Include a giant mecha bot that does all the work.
The BOS simply lost because they chose to fight the NCR and was defeated conventionally. There wasn't a giant robot scrapping their troops.
Think on this, no faction has ever come as close to total victory as the Enclave did in Fallout 2. They were just hours away from deploying the Curling-13 virus.
No faction has also come back again after three major defeats as the Enclave has (Fallout 2, Raven Rock-Purifier, and now AAFB). Although now they are likely reduced to a small force in Chicago, they are still around.
