Oh dear god do I hate Blackboard. The IT people at my uni wanted to use Moodle, because they could make it do what the university wanted it to do. The university just went ahead and bought Blackboard. It took them a decade to get it sorted (all the while Computer Science just continued to use Moodle for everything). Eventually they managed to get Uni to drop Blackboard. In favour of Canvas, which isn't much better.
