It doesn't make sense to us because most of the strong fans are close to Ayu and follow her and know what she is really like. But some casual fans and people who do not know her see a glamorous diva queen.
The catch is that whenever Ayu tries to tone it down people become disappointed and unsatisfied. They want bigger and better every year. Ayu is somewhat trapped inside her diva pop star persona. She kind of has to keep up appearances. No matter what she does, someone will be unhappy and have something negative to say.
The other problem is that Ayu has decided not to follow trends and make music she is interested in. I believe that once the whole idol group and Kyary trend dies out, there may be a renewed interest in what Ayu is doing.
The best we can do really is just mind our business and enjoy what Ayu does.
