OK, I have read many of the threads here and it is difficult (at least for me) to understand completely what is happening here. I have hundreds of ebooks in MOBI format and have now converted most to EPUB. Apparently Amazon is removing support from MOBI according to a message emailed to me today from them when I sent to Kindle a MOBI file. Many other messages here indicate that they are removing EPUB support as well. But it is very unclear to me what exactly "removing support" means? Will sideloading of these files still work? You know, a trusty USB cable and drag and drop? Or sending by Calibre or Calibre Companion? Or by "removing support" do they mean the Kindles will no longer be able to access these files in their library? Files which they have always accessed before (and now)? This seems to me (as a present owner of Scribe, Fire Max 11, PW Sig, Oasis 3, and a previous owner of almost all other, earlier models) to be absolutely insane of Amazon. The degree of the insanity is what I am trying to determine.
