There is a very simple way to disagree with Canonical's CLA: don't contribute.
Why it is worthwhile to write essays and talk endlessly on this 1985-era subject? Because too many people feel better if they can disagree with someone bigger than they are (in this case, Mark Shuttleworth) than they feel for actually getting down to some actual work.
If you do not like CLAs, don't sign them. Nobody is forcing you to contribute to Mir. Now go do something productive.
Much ado about nothing
