My counterpoint to this is just that DDB is not a super usable piece of software (it's slow, buggy, and expensive). It's got the massive advantage of having the rights to sell D&D content, but there's definitely room for disruption in that market.

They also have the advantage of the rights to create and use derivatives of D&D content, which unlicensed competitors don't.

Which somewhat limits the room for disruption in that (D&D-specific, not RPG VTT more generally) market.
