Does Canonical plan to start asking money for ubuntu in the future?

[Eragon]

It's the User Story for "Helen" on the software center wiki page:

"Helen is happily using Ubuntu 10.04 when it tells her that Ubuntu 10.10 has been released. Before she upgrades, she has some basic questions. What will the upgrade do? How long will it take? How much will it cost? Will she lose any of her files? What should she do if something goes wrong?"
(Emphasis mine)."

What do they mean "how much will it cost"? Does Canonical have plans to start asking money for ubuntu in the future? Or is this just a stupidly choosen example?

They pretty obviously mean that a hypothetical clueless user might have such a question.
