It looks like they just hope for it to be continued as open source - except for the part The Mathworks Inc. owns anyway
Going from my memory, "E-myth" book(s) insist on thoroughly documenting operating procedures and turning them into playbook. Rigid in terms of personnel training, but open to change if someone figures out an improvement. The goal is to be able to scale up operations into multiple venues (franchise models) while maintaining highly consistent appearance and level of quality.
As much as having such documentation will make it easier for a franchisee to get the business running (the books call it "turn-key business", IIRC), it will also make it easier for a potential buyer to take over and immediately hit the ground running.
But those will be different businesses. The restaurant will not make the same dishes or retain the same customers. The mechanic will operate on different types of vehicles.
If something gets cancelled, the 1 person company takes a few hours off. Your 3 person company still needs to get their weekly paychecks.
Whenever I hear calls for raises to minimum wage to absurd(?) levels (20$/hr), I think that this company will never be able to grow past 1 person. You can pay for a receptionist if you are a big corp with many employees, but it's really hard when you are going from 1 person to 3. We'd even let the receptionist do full WFH and just answer phones so they can watch their kids.
"I guess we don't deserve to be in business".
And the big corporation who gives 60% of our service conquers the industry.
