First, this violation only implies certain distribution of images, what you fail to mention completely. "Canonical insist that you must ask them for permission to distribute it" is a false statement. Personal and internal use is excluded completely and are always permitted.
Second, you state "The only alternative is to rebuild every binary package you wish to ship[1], removing all trademarks in the process." Again a false statement. Canonical has made it crystal clear that a solution using overlayfs on top of the official ubuntu image is 100% legit and as such always permitted.
Yet your title reads "Your Ubuntu-based container image is probably a copyright violation", which is simply untrue, a big generalization, and FUD. IMHO your personal quest damages the FOSS world more than the things you are writing about.
Is that so ?
