Okay so between a response from Epic here
and the roadmap
It is not perfect and we still can’t update our assets as there is no facility for a paid upgrade, discount for owning other versions or subscription
But they are at least addressing the hard stop regarding theft and copyright infringement.
So from our POV not that it really matters to others but just sharing our train of thought
We will keep what’s in place in place and when that version falls out of support we will delist from FAB. Hopefully sometime soon they will get a means to do paid updates in place so we can release our next major versions but until then we can at least wait and watch.
