ah, I wish I knew more Japanese so I could understand these. This seems to be part of an interview with Tsunku talking about the changing wota demographic?
The tweet has 27k likes and it's getting a lot of buzz from 5ch, so it must be quite the topic.
This is part of the interview included in the recent Morning Musume 20th Anniversary Official Book, the first part of which was posted just above your post. (Thanks jigenbakuda!) This particular segment is going to be in either part two or part three of my translation.
