I honestly don't know how to word this well enough to get my point across, but here it goes. Le Guin's in a nut shell is saying that using technology as a weapons will lead to tragic on a global level, but using it as a cultural bag could lead to a outcome that is beneficial for everyone involved. Words which hold meaning are a form of technology therefore in order to have the most realist settings and outcomes they should be used as carrier of information in a work. The best explanation that I can think of in which this is held true is the move Arrival (2016), which you guessed it is a Syfy.

Going off the VonderMeer side note here, I have not read Annihilation, but have seen the adaptation that was released in 2018. So I could be wrong it could be like the Percy Jackson Movie that was nothing like the book. Maybe Spoiler Alert The ending has the biologist begins to accept that the Shimmer is not there to attack and destroy, but rather to create something new through containing all of the people that enter it. This ending works well with Le Guin idea that viewing fiction something as a container/bag can provide a more pleasant outcome than viewing fiction as a weapon which leads to an outcome that is apocalyptic.

There are multiple agencies that have protected works that existed pre-technology and after each technological change. In the United States we have the National Film Registry, the Library of Congress, the National Archives and Records Administration, and some would even consider the Smithsonian as well.
