Since their inception SOPA and PIPA have raised concerns about blacklisting from online freedom advocates, and tech industry giants. Law professors worry that they could stifle growth and innovation. Other's have warned that the legislation would hurt scientific debate and open discourse on the internet. SOPA and PIPA are not without support however. In fact a wide variety of companies have backed the proposed laws, bringing together an eclectic group. After months of debate, the removal of one of the more controversial provisions, and The White House expressing its own concerns over the law in its current form, Representative Eric Cantor (R-VA) announced that he was shelving SOPA. PIPA however remains, and it is likely that a re-worked version of the House bill will be brought up soon.
