I had not installed it at the time of my previous posts. At the time, I was thinking that DeDRM 6.6.1 plus the KFXInput plugin would be redundant -- but now I understand that is not actually the case. I have installed it now -- and yes, conversion of purchased books is now working.

OTOH, it's kind of a pain to have to import and then re-convert books one by one before I can read them within Calibre (within the "E-book Viewer"). And the more I think of it, the more silly and annoying it seems to me to have a "book" broken up into multiple files as KFX does it. Get off my lawn, you young whippersnappers!

I am now appreciating more fully the differences in the solutions going on here: Methods 1-3 in the "Dealing With" thread are ways to avoid KFX altogether, while Method 4 plus DeDRM 6.6.1 is how to deal with KFX once it is foisted on you. After reading up a little more on KFX's benefits (enhanced typography and image handling, apparently), I'm thinking those benefits aren't really worth the added hassles of dealing with the files.

TL;DR -- I went ahead and used the chmod technique (Method 2), and all is well for now. Much simpler to deal with the files this way.

Thanks to Terisa, jhowell, and pdurrant for your input.

Of course not. Silence is always a viable option. It's just annoying to post on a thread titled "Handling KFX Files in Calibre" and then be told that the thread is not actually an appropriate place to ask for help with handling KFX files in Calibre.

So far as removing DRM from KU books go, payment to a particular author by Amazon for pages read does not entitle you to keep the book concerned.

Converting a book in Calibre does not necessarily imply keeping that book on a permanent basis. But ethically your point is a good one, and could engender some interesting debate in an appropriate venue.

We don't know precisely how Amazon determines pages read. A recent statement from Amazon implied that at least newer Kindle devices (and presumably apps) can determine with a high degree of precision what pages have been read. Whether simply quickly clicking through on such a device is sufficient to trigger payment to an author on such devices or apps only Amazon knows.

This is true, and it's a good thing to keep in mind. OTOH, it seems very unlikely to me that Amazon has some sort of timer on KU files so that if you click through a page too quickly, it doesn't count as having read that page.
