Hey-ho. I'm a Bb admin going back to CourseInfo 2.x. (That's coming up on seven years.) There are a couple of very active listserves run out of ASU for Bb users and administrators. Most of us use the lists and their archives as much, if not more, than the "official" Behind the Blackboard tech support site.
When the announcement hit, there was the expected flurry of oh-my-Moodle and gosh-golly-gee-whiz reaction, with similar splits between the "hey - it's sliced bread!" and "hey - it's the end of the world!" points of view. (My own reaction, as I forwarded the announcement to the list, was simply, "Whoa!") The discussion quickly migrated over to the BB-WEBCT-MERGE list hosted by OLN.
