I’m not sure why you’re being so cynical 
It’s the same concept as this In-Game Tablet with Web Based CAD/MDT Support but its far, far simpler.
This is a download and go version of that one. You don’t have to trim this down at all. I made this myself. The only code I used that I didn’t write myself was the the drag feature, I also adapted NUI resources code. I used the code from How To Create a Draggable HTML Element because, well, why the hell would I recreate code which I can use for free, saving myself time and effort? My use of their code was not for profit of any sort. I simply wanted to fufil a need which I had encountered before I developed this. (A simple iframe tablet) I just said “hey, heres a simpler tablet”. No malicious intent, no blatantly “stolen” code from resources which specify against usage of their code for research/teaching (the primary purpose of this resource was to teach myself NUI).
If we comb through every resource which uses code from online teaching resources on this website, I fear there would be very very few resources left.
Just out here stating this is already released exact same thing as someone elses work does the exact same thing
This is not the “exact same thing” as the other tablet.
So again, I’m not sure what the problem is.
