My recommendation to Cloanto would be to allow the videos to be distributed, but with a Cloanta watermark or intro/outro screen.
So it stays available and possibly drives some business their way.
Maybe even tell youtubers that you can use some of our clips, as long as you mention that you got them from Cloanto somewhere in your vid...
I'm really glad they are now distributing (allowing distribution of) Workbenches and Kickstarts..
So I'll stay positive on this..
But that's just me... :-)
