How much did you donate when downloading Ubuntu 12.10?
For about three months already, when downloading Ubuntu, all users are invited to download Canonical before downloading, some amount of money ($ 16 by default).
At the same time, users can choose for themselves exactly what they would like to transfer money (by default, all 8 options have two dollars selected). By selecting a certain amount of money, the user sees how this amount can be compared (for example, the amount of $ 30 is compared to the cost of stainless steel pans with a copper bottom, and the amount of $ 500 is compared to the cost of a ticket from New York to London, one side).
