I get the attraction guys, I really do. But to make and improve a good product requires a financial surplus, this ONLY comes thru a consistent money flow.
Imagine I say the following to you, as my employee: "We will probably make enough money, to pay you at least 10 out of 12 times this year, that is our hope, or I will reduce the staff to a 3 man team".
The subscription model allows me to say to you: "We are doing great, we have a strong subscription base, that allows us to forecast, a consistent flow of capital, and even enough to greatly improve the product, which will allow us the opportunity to hire additional help, and commit to overtime pay also"
