In most of the blogs where supposedly you can download books, when wanting to download a book that has caught your attention, instead of being able to download it and already, they send you to another page, they will require your data, in some I found that they ask the bank card and the data from it, and finally get tired and leave.
If it's free, it should be free, without requiring much requirement ...
The same happens when you want to download some free software.
I think that free internet should be free of truth, that is, without requiring all data.
And you do you think about that?
