I belong to another gaming group that does not use Fantasy Grounds. They want a more “minis in a 3D world” view than FG provides. They use D&D Beyond as their game manager.
D&D Beyond allows collective sharing of content. Each of the other players owns some book or books and shares their individual content with all the other players. And it matters not whether they do or do not attend every session.
The point being, WotC is allowing a collective sharing of there content (managed by D&D Beyond). And this has been this way for some time (prior to DDB’s acquisition by WotC).
So there’s hope!
