If you want a detailed explanation of the Amazon show, I did it in this post here but the short answer is it's actually good and not really woke at all.
This post is more discussing a something that looks to be the future of the franchise in terms of lore so there will be spoilers for the show.
Basically in the show, ALL lore related to Fallout New Vegas has been erased. The fractions are either not mentioned at all or severely diminished in terms of the NCR, some things in 1 and 2 have been changed (like Vault 15 which Shady Sands was built around is not mentioned at all) and it looks like they are only using the setting of New Vegas in a season 2 as they show the strip at the end of the season.
This is one thing, but I also recently heard of a Fallout 4 update and DLC planned where the update is optimising for 'next gen' consoles and the free DLC will introduce a new fraction to the commonwealth to stop...
..the fucking Enclave...
They seem to be only keeping lore cannon completely in Fallout 3 and 4 so does the Legion exist any more? Are the Followers of the Apocalypse still around or they gone too? Does any of the characters we liked from New Vegas exist either like Boone, Veronica or Cass?
The other thing that urks me is Fallout New Vegas was the best written and world built game in the franchise in competition with 1 and 2. The fact they are bringing back the Enclave for 4 just makes me think the writing staff at Bethesda aren't that creative at all and they're just rehashing old plots again and again than try some other direction or a new take on an old fraction. It's REALLY not giving me hope for Elder Scrolls 6...
TDLR: Bethesda may be doing what Disney did to Star Wars Extended Universe and erasing lore not made directly with Bethesda
I was looking up the Wiki so might've mixed them up there but wasn't Shady Sands descendents of vault dwellers anyway so there was a vault near them?
From the way they portrayed it if I go off the geography view from the observatory base in episode 8, the hole were Shady Sands WAS is slap bang in the middle of downtown LA so did they mix it up with Bonetown and then do the Followers of the Apocalypse exist anymore?
I put it down to bad writing that they wanted to sideline New Vegas because:
Was showing up the Bethesda only Fallouts in terms of writing, characters and world building
The NCR was TOO powerful to have as the underdogs if they kept it and the West Coast Brotherhood wouldn't be able to be so prominent if that were the case.
Oh I agree you're completely on the ball with them trying to wipe out pre-Beth canon and NV, especially as in F2 the Brotherhood was near non-existent on the west coast (There was mention of an expedition East), but of course Todd wants all the familiar from Fallout in order to sell (The over the top 50's vibe wasn't really a thing in 1 and 2, but did exist to a minor extent, Supermutants were also near extinct, but "Somehow they returned", bottle caps were a currency backed by Water and the Water Traders in the OG, NCR had it's own currency going by 2, and plenty of other things)
And yeah, Shady Sands was made up of the dwellers of Vault 15, but they split into factions, with the rest becoming raider gangs like the Khans
