It is not a "tourist attraction" but a sombre and melancholy memorial and warning to history of the evil of which amnkind is capable.
The Polish authorities are not responsible for the behaviour of visitors. If people behave inappropriately here, then one despairs, but what do you suggest?  Arrest them for taking photos or talking?

1.  Visitors   to   the grounds of   the   Museum   should   behave   with   due   solemnity and respect. Visitors are obliged to dress in a manner befitting a place of this nature. 
2.While on the Museum grounds, visitors must adhere to the instructions of the Educators and  the  Museum  staff.  '"
Visitors in groups are required to engage an Auschwitz Memorial guide, but Individual admission to the grounds of Auschwitz-Birkenau is free of charge. For better understanding the history of Auschwitz-Birkenau they suggest a visit with an educator/guide and as a reasonable tour of the site would take I would say at least 4 hours, I would heartily recommend it, as the guides/educators are very knowledgeable.  But you do not HAVE to pay, you are free to enter and spend all day there for nothing if you don't want a guide. 
It is a pity it can't be made compulsory to visit.  The place leaves something of an indelible mark on most visitors, and while some may mock at the mountain of shaved off human hair, (and when we went, we never encountered even a whisper of poor behaviour from the many  hundreds around the site) I felt  despair at the thought of what that hair was, and the awful fate of the human beings to which it once was attached.
