Based on their decisions they might as well just get on with it and ban Bitcoin every week.
As for Tor, can they even actually use it? As using VPNs are illegal as far as I know.
They will probably do that when there's more companies that will get in the bitcoin, this ISP blockade can essentially make companies regret their investment in bitcoin which might cause for some of them to pull out making the prices go down. I think that GFoC jumpers are using Tor to get out of the censorship.
