Commercial Indy License for HTML5

[Kevin Miller]

Right, its not exactly going to be practical to take it apart. As we
develop this we¹ll be looking at obfuscation to make it as hard as
possible. Nor would you have any right to use the code or redistribute it.
So there is a practical difference and a difference of intent. If its
commercial, you¹re hacking which is hard and the original author can also
look to appropriate law for protection.

GPL is quite different. The HTML5 output on the page is the Œcompiled
form¹ in GPL terms. The HTML5 compiled form is not the original source. It
would not be considered to fulfill the terms of the GPL. The GPL binds you
to releasing the original, modifiable source code. Everyone who receives
the app - I.e. everyone who visits your web page - has to also be provided
with the opportunity to receive the original source so that they can
modify it and redistribute as they choose.

Imagine you are contracted to produce a web app for a company to log sales
from your network of sales people and affiliates on the road. If you give
that to the client under GPL, they would need to include a link within
that app to download the source code and anyone could take it and use the
entire app freely. That is hardly going to be acceptable. There are lots
of other such examples.

Kind regards,

Kevin
