People tend to project their personal preferences with an aura of superiority to the unknown future when everyone will ascend to their level and reach enlightenment.
For what it's worth, I think he is most likely correct that 20 years from now, any discussion of Dune and its adaptations will call Lynch's version "inventive, but flawed" and Villeneuve's "drab and lifeless, aimed at movie-goers who had freshly aged out of Iron Man and wanted to feel like it". I can practically feel this article stare at me from the screen already, too. And it probably wants to provoke a little. If anyone still cares, that is.
The reception of Lynch's version will continue to be colored by his overall ouvre, and it's all just so much more interesting and charming for anyone who has to see and write about movies all week long.
