They said this devalues FF11 and gives the impression that it's unable to stand on its own.

So for better or worse OP, we can expect they will never make a joint subscription like you're requesting.
In terms of actual content I think FFXI actually dwarfs FFXIV. However FFXIV had better presentation to the mainstream gaming audience after its 2.0 launch that made it's playstyle more similar to other MMOs. Then again FFXI could just feel like it has more content because all the content isn't completed in a few hours so players spend more time actively doing things to complete them.
