That until the old reddit is deprecated. They want people to go ahead use the new interface because it makes it much easier to insert ads, track and do who knows what kind of other shenanigans..
The thing is for us who've known a better and more usable internet, we have something to compare it to and simply say no. The newer generation of users accept it for what it is, they don't know better.
Something else irks me quite a bit as well, and that is when you can't copy a link from the page or when the history is messed up when going back. It seems utterly broken, and most of the time the design is as well (but that is somewhat subjective)
