It appears that the author is expressing the position of Project Gutenberg. Is this the case? If not, then I believe he needs to use the same communications channels available to the rest of us.
I would be all FOR an open and honest comparison of ALL the REAL advantages and disadvantages of each of the current ebook reader crop and ALL the real "good for the public domain" vs. "crappy monopolistic" behaviors of each of the major vendors. Buying a real machine today requires a series of hard compromises - including for most of us "loving the one you got." Not that we could ever agree on such comparisons. Thank god for all the real choices buyers have today - including god knows how many different Taiwanese Android tablets on sale close-out through discounters if only one had the time and energy to figure out how to make them all work, IF they work. Personally, if I had all the time, energy and money in the world - and didn't have a wife taking a jaundiced eye at all my "toy" purchases - I think the Nexus 7, the Nook tablet, and the MS Pro Surface all look like fun toys. But one has to actually TRY these things in stores and see if you can actually make them do anything useful. And at least in my case the salespeople always get suspicious as soon as I make even one trial attempt to download a book direct to their store sample from PG and then chase me out of the store -- *nobody* actually wants you to buy their device to use with *free* books!
