Barence writes to tell us that Canonical plans on limiting the number of "free Ubuntu CDs" that people can mooch from the company. The growing popularity of Ubuntu has seen a dramatic increase in the number of CDs being shipped via the free "ShipIt" scheme. The only people able to take advantage of this program now will be the usual community teams, contributors, and first-time Ubuntu users. "'While these CDs are often referred to as 'free CDs,' they are of course not free of cost to Canonical. We want to continue this programme, but Ubuntu’s growth means that some changes are necessary. Therefore we are adjusting how we handle CD requests to try to find the right balance between availability of CDs and the continued viability of the ShipIt program,' [Canonical's chief operating officer Jane Silber] adds. Extra CD copies of Ubuntu will still be available for purchase through the Canonical store, although they need to be bought in bulk. Five copies of the open-source operating system will cost £5 exc VAT and shipping."
