I don't understand the negative feelings towards proprietary web frameworks. We offer a product that solves a problem. We've been working at it for 6 years, have invested hundreds of thousands of dollars into R&D, and have numerous free options for non-commercial projects, including free educational, non-profit, developer, and open source project licenses. Compared to our competitors we're leaps and bounds ahead of them technologically, and we undercut them on price significantly.

Really, what more can we do? Do you not use a tool because there's a company behind it providing support, up to date documentation, and other resources? We even have a clause that says if anything should happen to us, all the source is opened.

It's unsettling that many developers who charge for their own services and products let out a sigh when other developers decide to charge for their services and products.
