This is a frequently repeated idea, but I think it's an exaggeration. It's true that git is popular, but both CVS and subversion are still widely used for many projects, and both bzr and mercurial are continuing to grow in use. Proponents of git tend to repeat this idea that "everyone will soon be using git". Many of these proponents are kernel developers; from their perspective, it often seems that everyone is *already* using git. :) And unfortunately there isn't much survey data to tell us what the real market share (or mind share) of the different VCSes is; but at least one attempt at finding data shows that bzr usage is growing much faster than git usage: http://bazaarvcs.wordpress.com/2010/02/15/bazaar-adoption-growing-strongly/ Now, to answer your real question. :) Linaro uses bzr in large part because Linaro uses Launchpad, and Launchpad integrates with bzr (and it does not integrate with git). Some of us on the Linaro team also have a personal preference for bzr, so this works out nicely for us - but it's not something that we're religious about. For collaborating with certain upstream projects, such as the kernel and u-boot, it's clear that using git is the appropriate choice; that's why we have git.linaro.org. For new work in Linaro, such as our platform and infrastructure tools, bzr is the better choice because of the integration with Launchpad.
