Hardly. One Bitaxe represents about 1/1,000,000,000 (one one-billionth) of current global hashrate. Good for learning or playing the solo mining lotto, though.
I guess a similar thing can be said about relays.. :) With relays the model is even more different: only 1 relay needs to be censorship free so the network is censorship free. If the probability of 1 relay censoring is 10%, then 2 is 1%, 3 is 0.1%, and 10 is 0.00000001%.
