It is possible that the original article is no longer accessible online.
The only link I have found is a reproduction of the article[1], but I am unable to access the full text due to a paywall. I no longer have access to academic resources or library memberships that would provide access.
My Google search query was:
pussification of silicon valley inurl:upside
which returned exactly one result.
I suspect the article's low visibility in standard Google searches, requiring operators like 'inurl:', might be because its PageRank is low due to insufficient backlinks.
