Why the Internet exists?

[Vi]

The Internet is not private. Any site has the duties to provide best services, especially if promised, regardless of the site existing for free or for payment.
I would prefer it exists for education and entertainment.
Recent observations show however nowadays the Internet turned out to be for torture and suppression of any free idea and mind, supposedly worldwide. Things need to be done.

The internet existed originally for government/military use and educational use. As the technology grew, it began to be used commercially. Now it is used for those purposes as well as private/personal usage.

Like Pandora's box, once opened, it is open, for good or ill. It is like any tool: it in itself is not good nor evil. That only comes from the people who make use of it and how they do so.
