Dune was rumored to be unfilmable with the Lynch movies and SyFy miniseries costing more than they made. No one followed up Dune with a twin film because no one thought it would be good and draw in non-nerds.
With nothing to compete against, Dune was able to be the success. Dune may have set off a minor sci-fi production push but nothing like the Star Wars generated sci-fi hype train of the 70s and 80s.
Also, Foundation is owned by Apple and part of the content for AppleTV. Dune may very well not move the needle for execution producers to spend effort and money on sci-fi properties.
