Till now the discussion is focused on "T&C" set by companies and Legal aspects of the digital Content .
Let's take out legality and the absurd T&C , and bring in some Practicality to this discussion .
Practically speaking it is weird that you are only licensed to a particular digital content and the company can withdraw that license anytime.
And it has happened to someone . He was traveling to Singapore and as soon as he reached there all of the digital content i.e. eBooks he had bought vanished, as it was a no eBooks zone.
This is ridiculous. If I had paid for something, I fully own that thing .

The T& C set by the companies are always according to their own convenience .
If any thing is done out side the purview of that it becomes illegal.
