If you bother to read my post, I have certainly accepted the fact that I made an error -- a "complete mistake," as you so curiously phrase it (as though there were any other kind). That has never been at issue.
I also stated, quite plainly I thought, that my dudgeon is over the lack of any such annotation on the main featured advert, the one just under the new Dakota. It seems to me that the Archer should have been clearly and obviously labeled as being solely for FS9/2004 -- and not dependent upon a line buried in the text of a subsequent page.
Dream Fleet is a commercial operation, and, as such, should be held accountable for the clarity and accuracy of its advertising, just as any other commercial enterprise should be. I see nothing "immature" about admonishing the publishers of the website to clearly and accurately mark their products.
Further, it would seem your definition of "harsh" is other worldly. Nothing in my post could conceivably be considered as anything other than an honest criticism, as it was intended to be.
