Sure, I forgot about those. Those are homebrew kits, nothing to do with the IPA you buy at a pub or bar. You can't make a sweeping statement about IPAs based on those.
I'm not sure how "IPAs aren't real beer and are made from concentrates!" ends up at "There's a company planning to ship all sorts of beers in concentrated form straight to the end user", but there was a change of direction there somewhere.
