Are Chinchillas farmed for their fur?

They are first kept in small wire cages which they should not be kept in (I own 2 chinchillas) they are then grabbed by there tails and there necks are broken but they are still alive screaming and squirming around in pain they are thrown on the ground by people who just don't care about them. There are videos on YouTube that you can watch. Im sure there are other ways of doing it but I saw this done its very sad especially for the people who own them and know how affectionate they are they are very loving pets.
