Step back, connect the dots, and see the big picture of the pink elephant in your living room.

Many file hosting sites steal your work with their license scheme. They make you agree to let them own your work.

Don't be a slave of THEIR system, be free, and just share your work in a way that the corporate sharks never have the 'right' to claim ownership of YOUR work.   Their laws are from another century, and they didn't make any progress in the last 100 years. And they probably don't want to make any change either.  This revolution doesn't need guns, it just need people like you who use their minds and say NO to the old way and show the new ways and make them work.

Sharing is one of the the first thing a child learns, so why should they stop sharing once they become a teenager?

Your mother didn't teach you to be a greedy bastard, or did she? So why do government's support greedy bastards?
...RIGHT, because THEY are greedy and sometimes (often) even corrupt.

Stop the thievery corporations, and CREATE YOUR OWN FREEDOM.  

MAKE IT (with these bots)

Now here is an option:

• Make a tarball of the files tou want to publish
• Include a Creative Commons (or other) License
• Host your own files on your DSL
  
• make a torrent, magnet or whatever link to your files
• SHARE THAT LINK on a site, BUT NOT THE FILES THEMSELVES

Then there is NO NEED for thingiverse and the like who can claim ownership.

And maybe there are even better ways, but consider this option as a start.

You can also host your own files with Mediagoblin.

http://mediagoblin.org and http://mediagoblin.com

Mediagoblin is the free (as in freedom) alternative to thingiverse, youtube, flicker, soundcloud. etc.

Instead of being held hostage by a EULA that might disrespect your freedoms you can host your own files and always have complete ownership of your own work and still allow others to share and improve.
