I agree. One of the biggest selling points of bitcoin is that it's free of this sort of censorship from banks or credit card companies and they only shoot themselves in the foot when they do this sort of thing and it spreads adoption to bitcoin in the process. Hopefully more companies will get involved whether they're censored or whether they're just sick of paying extortionate fees to payment processors and credit card companies.
The problem is that unless you get paid in cash, you still need banks to gain acces to bitcoin.
I think it is a brave but wise move from back page. It will also greatly increase bitcoin users if they need to pay them in bitcoin for the ads.
