First of all, I am an unashamed francophile.
However, I am having a hard time understanding the rationale for the push for the usage of word "liseuse" in English for the following
raisons:
- We already have a perfectly good, descriptive, word in English, namely "ebook reader".
- "liseuse" has no cognate in English making it difficult to remember, and meaningless to the uninitiated.
- The lis, sorry, ebook reader is not a French invention.
- Do you really want to see, or rather hear, another French word get mangled by Americans? The people who turned Notre Dame into "Noter Dayme"

By all means campaign for its adoption into Le français, just don't forget to ask L’Académie nicely.
