In the research that has been done, over 90% of passengers travelling in Upper Class travel alone and on business.
The ones that do travel with someone are usually business colleagues and they stated they didn't want to have to sit and "chat" to someone they work with for the whole flight when they are more than likely going to be stuck with that colleauge for the duration of their business trip. They would rather be able to use the time on the flight to sit and relax and watch a movie or sleep etc etc.
The percentage of non business passengers travelling together is extemely low - and believe it or not are usually staff on staff travel !!!.
So for a majority of people the seating layout is pretty good, they have the privacy for the single passenger and for people travelling together there are a couple of rows where they can sit and face each other and for the business colleagues they have the option of using the ottoman if they do fancy a chat.
Obviously it won't appeal to everybody, but the current J2000 seats don't appeal to everybody either. No matter what an airline (or any company for that matter) does there will always be a small percentage that will complain.
As the old saying goes, "You can please some of the people some of the time, but not all of the people all of the time".
