The culture of WHT and subsequently NB is incredibly black and white toward generating a profit. WHT is a company, and they will do whatever they can in order to generate those profits. If that includes censorship and aggressive actions toward users then they will do that.
0x00sec is different because our motivations and work is all done around and for the community, rather than to make a profit. We will never censor a post, unless it contains something sexually explicit, personally identifiable information etc. We don't delete posts because they might make us look bad; we agree than information should be free, and if that means somebody has created a badass rival site, then so be it.
