Well, all I can do is quote this section of the article as to why Persson was ignored after her communication attempts:

'(A spokesperson for Furuvik Zoo told me that that they didn’t take Persson up on her offer because they believed that “those currently working with us are the ones who know the chimpanzees best.”)'

I don't think she would have been permitted on the grounds for ideological problems, in addition to legal liabilities.

...and I'm upvoting your comments, as the ratings above aren't fair.
