...the important thing is that ZOS was not involved with the development of Fallout 76 in a significant way...
Zenimax Online
was directly involved.
Here. Skip to timestamp 05:08 to hear it from the horse's mouth. The thing that would have been weird is if they had NOT been involved Fallout 76.
This is partially why a parent company like Zenimax invests in so many different studios: it allows them to utilize a wide range of talent on whatever project they think will be most successful. I don't adopt studios, then send them to their separate rooms to do whatever they want. I give them all chores to do whatever I think is best overall. If I think Studio A needs more help on their homerwork, then I simply assign Studios B and C to spend an hour a day tutoring A. They can't say no, because I also pay their allowances and can toss them out at will.
Zenimax Online was directly responsible for creating TES: Online, and they didn't exactly have an easy time of it. But, they did get their ducks in a row, and TES:O is more successful now than it was at launch. They were also working directly with Bethesda's IP, which clearly means that Bethesda's studios had a working relationship with them. Probably a very close one.
So, let's talk business sense, now. I have a team that learned (the hard way) exactly what sorts of mistakes you could make launching an online title, and exactly what could be done to fix them. I decide to invest in a new, online game, based on a
hugely popular IP, that will be developed by one of the most inexperienced studios in my conglomeration...
...I'm going to choose
not to have that studio work closely with the highly experienced one to ensure the game is a success. Or, I'm going to fail to effectively utilize any of the other studios I have to support the project. And, I'm going to rush it. And, I'm going to upset a tremendous number of patrons and customers by releasing a cash-grab instead. And, I'm going to knowingly damage my reputation by engaging in numerous malpractices after the fact.
Then, I'm going to start advertising my next game.
Nah...
I might cancel the project. I might delay it or re-brand it as something else later. I might sell the studio. But, for things to go as south as they went -- I say something went
hella wrong somewhere, and the only thing they could do was try to crash safely. Maybe it was corruption in the ranks, infighting or some sort of sabotage, a totally unexpected legal issue...but I refuse to believe the company responsible for Morrowind, Oblivion, Skyrim, Fallout 3 & 4, TES: Online, Dishonored 1 & 2, the DOOM reboot, Prey, the Wolfenstien reboot...would intentionally screw up this badly.
