Linked Data tends to live in a semantic web world that has a lot of open world assumptions. While there are a few systems like this out there, there aren't many. More practically focused systems collapse this worldview down into a much simpler model, and property graphs suit just fine.
There's nothing wrong with enabling linked data use cases, but you don't need RDF+SPARQL+OWL and the like to do that.
The "semantic web stack" I think has been shown by time and implementation experience to be an elegant set of standards and solutions for problems that very few real world systems want to tackle. In the intervening 2 full generations of tech development that have happened since a lot of those standards were born, some of the underlying stuff too (most particularly XML and XML-NS) went from indispensable to just plain irritating.
