Well, basically the requirement (request, if you prefer) would be to be able to use essential functionality of the customer portal (I don't have a list at the moment) without needing to run JavaScript code in my Web browser that is not "free" in the free software sense of the word, i.e., providing the four canonical freedoms:
http://www.gnu.org/philosophy/free-sw.en.html(JavaScript is a bit of a special case, since some JavaScript is "trivial". The "JavaScript trap" article referenced previously gives some clarification on that point.)
I can disable RC JavaScript with a plugin (such as noscript) but then the portal becomes totally non-functional (after login). All content fails to load except an empty box.
I'm not especially familiar with your code, but I think the main thing to be addressed would be your RCLibX code, and maybe some of those large blocks of inline JavaScript, if you wanted to make your JavaScript free. There are different ways of handling the licensing (see the javascript trap article) but with GPL licenses I believe you could just have the source code in a public repository some where (properly licensed) and then embed a link to that repository in the delivered code.
Alternatively, you could construct a fallback interface which requires only free JavaScript, or no JavaScript at all. Of course, it would be great if free software advocates got the same pleasant interface experience as everyone else, but either solution would be satisfactory to me. E.g., the search engine "duckduckgo.com" has a main interface that uses their proprietary JavaScript, but they also have a fall-back HTML-only interface:
https://duckduckgo.com/html/
As much as I would love to open source all code, there are crucial business use cases which prevent making all components of code "free and open source".
I understand your request and have shared it with my leadership for consideration.
If I receive notice that they have agreed with you, and have prioritized implementing your request, I will update this thread. Thanks for your dedication to the open source community values. :)
