I dislike CFs role in the modern Internet as much as the next person, but this is a bunch of speculation trying to connect dots with no basis other than that a Canonical cert renewal happened on the same day as a company transfer.
There might be somewhat of a tangential story, however, in that Njalla seems to have reorganized or changed ownership fairly recently[1], and that Njalla and immateriali.sm seem to be related entities[2]
