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
Seems like they're downplaying NV out of spite? It was the obsidian one, the one bethesda relinquished a degree of control over, and it's the most fondly remembered of the new fallouts and its not even close.
I REALLY wouldn't put it past them, a lot of the current crop of writers in the west will erase previous works that they can't compete with when they take over a franchise to mitigate comparisons not realising it can cause a Streisand effect.
Even though Bethesda published it, gave Obsidian a ridiculous time frame to create and goals for a bonus, to have that be recognised as the best of the first person Fallout's probably a huge sore point.
Might be some kind of niche copyrights/royalties thing, although usually when that happens it's because an IP's been split up into different parts between different IP holders.
Which is funny. It's pretty much universal that NV is the only fallout that people bother playing as opposed to 3 and 4.
