I applaud these guys.
It's more about the money per se - it's about having a share of company profits. This, I find, is what a lot of companies get wrong. We go by the same old mentality that an "employee" should simply be compensated with a fixed amount. But why? People who work on the product should have a significant share of the profits as well. Allegedly a regular employee is "taking less risk" by having a fixed salary as opposed to the "risk takers" at the top - but in this day and age where there is no more guaranteed long-term job stability, that is not true anymore. And the continuing success of the company's products depends directly on the good work of its employees.
