I admire the intentions and the hard work behind this however...<p>The issue I have with pay-what-you-want or low revenue business models is they&#x27;re unsustainable.<p>Either declare something a passion&#x2F;charity project and make it complete free (but perhaps open to receiving donations) to properly set users&#x27; expectations or monetize it.<p>I takes a lot of time to develop and maintain complex technology like trading tools.<p>I don&#x27;t know what the founder&#x27;s background is. However, if he makes good money from other sources, after the initial euphoria of sharing his tools with the world goes away, he&#x27;ll have stay motivated doing the grunt work to maintain it. And pay out of pocket for expenses and the value of his own time a PWYC pricing model likely won&#x27;t cover.<p>Making money (and a profit) isn&#x27;t evil or bad, it&#x27;s necessary both to see if your market (and audience) deems your product worth developing and to keep yourself motivated (and compensated fairly enough) to work on something.<p>A lot of companies have shut down due to lack of funds (or the ability of makers to go without making much money). It&#x27;s risky for an user to try a product with a tenuous future, come to base their work flow on it only for it to be closed down down the road. Especially with something like trading.
