The html5 and lite wallet code is not open source yet because, as you can understand Shadow is trying to build its foundations first and allowing a cloner to copy its code is detrimental to it first gaining the attention it needs so that people can work on building on the code instead of straight up cloning it and not adding to it at all.

The process of building a solid foundation is almost set and now is the job to work on gaining the recognition the dev team deserve so we can see it all open source. but only when its not a doubt in anyones mind "oh shadow team made that feature, nice"

Here is a image of the html5 ui that has a sdk being built right now for app devs to leverage.. Take note those are animated gif! Implementing a pos wallet into a mobile device is no easy step nor is spv lite wallet in pos code. Its why it has not been done to date..Peercoin, i believe they still have a 20k bounty for a working pos mobile wallet. They do not have a pos lite wallet still. So i'm sure you can agree this has already  been mischaracterised by thelonecrouton and has far more substance then the opinion you first have by building its source. Evan believes it does and so do the mature community and team behind it, i encourage you to look a little deeper.
