There's nothing wrong with that—this is the open source world, after all, and many people contribute to Ubuntu with code rather than money. But starting this week, Canonical is presenting desktop OS downloaders with an optional donation form... Once you donate, the Ubuntu desktop starts downloading. Or, you can just skip the donation and download the OS for free, just as you always could. For some reason, the donation page is not presented to Ubuntu Server users.
