Third, they need to slow down the pace of work so the employees can focus on quality and accuracy.

The rate at which they pump out content is, in my opinion, unsustainable for the employees and unsustainable for the semi-regular viewer as well

It may've been sustainable if they had all 120 people (or more) working in groups on videos, but at this point there's a question to be asked if at this point they're tech youtube channel or full blown video making company.
