Scientific Linux remove logos, the name "Red Hat" and rebuild binaries when making their releases derived from Red Hat software.*
I believe that SL started doing this after Oracle shipped a modified version of Red Hat Enterprise Linux (possibly an alpha or beta release) with the Red Hat branding and Red Hat got annoyed about all the support calls.
I don't know how much of this is required by the Red Hat licence, but it does sound rather similar to what you say Ubuntu requires. But then Red Hat Enterprise Linux does not claim to be free software; is that the point, that what Canonical is requiring makes Ubuntu like RHEL rather than SL ?
