Bethesda jank is what brought us the Giant Space Program in Skyrim so I'm definitely fine with some jank. They've also said it's the least buggy Bethesda game they've made. It feels like you're just picking bad points to shit on the game.
Are you arguing against it? Has anyone actually done an in-depth analysis to prove that the games are not getting less buggy? I know Bethsda has a vested interest in us thinking it's true but without any evidence I'd trust them over random people on the internet.
Fallout 76 is extremely different technically from their single player games so of course it's going to be more buggy. I'd be more interested in a comparison between Skyrim, Fallout 4, and Starfield after it releases. Also the "It just works" quote comes from Fallout 4 talking about the settlement builder. I don't know what claims they made about FO76 since I wasn't interested in it but I doubt he would use the same phrase again after it backfired so bad (and I also can't find any evidence he did say it for FO76). So no, Todd did not "literally say" it just works. In fact for FO76 he said "sometimes it just doesn't work".
He said that as a joke while announcing the BETA of Fallout 76. And after the beta they announced they would fix everything, which they obvioulsy didn't.
Jank is partially the result of allowing for emergent gameplay where various forms of simulated systems can interact with each other in novel or unpredictable ways.
That being said I have no clue how people tolerate playing these games on console. Can't even count the number of times I've had to use console commands to fix something myself.
The fact they are priming people to expect this is pretty bad.
