I love the Jackbox games.

However in my experience most games's shared world state cannot be reconciled if one player's action is inserted in time prior to another player action. Or future actions reveal hidden information.

Even turn based games have turn timers. Including Jackbox games!

Among public databases there may only be two correct CRDT implementations in the world - Cassandra's and etcd's. Compare to how many database products make CRDT or CRDT-like promises, and how few probably actually work.

Lots of software promises CRDTs-like-over-actors, e.g. Erlang, the new Cloudflare product. Not really qualified to talk about them.

Most applications normal people use boil down to chat conversations - chat apps, Gmail, Facebook, collaborative text like you said, all sorts of log-like things - or serial, recommendation-driven consumption - YouTube, Netflix, which use incremental / batched cells in a matrix to update their recs. This stuff is insensitive to order and time. Then there's e-commerce, which is inherently linear, centralized, single-actor, all-or-nothing transactions, CRDTs provide no advantages here.

It's tricky. On the one hand you'd get this interesting discussion of CRDT applications. On the other it may wither under intense scrutiny.
