The difference with this company is the *sharer* gets a piece of the profit
Whereas all the other entries listed use "sharing" means "You share your stuff with us and we share the profit we make from it with our stockholders."
The fact is the formal part of education in technical subjects often covers "reasoning from 1st principles." On the job a lot of work is done by "inspection" methods. IE Look it up in a book/on the net.
The point of teaching from first principles is to be able to handle the situation when it's not in a book IE you have to invent a solution. It also allows you to estimate if something is good enough in a certain set of circumstances or if the source is actually wrong. That's Back-Of_The_Envelope reasoning. In Programming Pearls the author showed showed a BOTE done before starting detail design on an email system showed the system would need a 28 hour day to work.
But sharing (or as it's know in business teamwork) is not really taught very well at most level to the extent people really practice it and get comfortable with it.
