It's not about being a fanboy if the model works with two companies why wouldn't work with a third company?
The 80/20 rule has been documented to death.
Besides 80/20 rule being bullshyt, that model "works" with the other two companies because they're much different than Twitter.
First they relied heavily on government subsidies which helped paper over Elon's fukk ups. Second they are in very specific fields that didn't have too much competition and career options at the time. If you wanted to work on self driving or in aerospace engineering you might be willing to suffer for a few years, especially since you're waiting on your stock options as well.
Twitter employees are not going to accept that bullshyt. Elon already tried his favorite gambit to fire up employees, he announced that company might go bankrupt and it had a completely opposite reaction at Twitter, people became even more disillusioned. You are forcing people working from home not just to come back to the office but also to take on additional work and extra hours
They'll rather take their 3 month severance than work 70-80 hours per week for no additional benefits.
