So has Wikipedia: they could have just dropped GoDaddy without saying a word, that would have been neutral. Publicly proclaiming you severing business ties for a politically-charged reason is just bad business.
"publicly proclaiming" is 'as discussed in our own online spaces where we came up with the decision'? Do you have evidence of wikipedia seeking out other media to promote their decision?
I don't see that as bad business. Wikipedia requires neutrality. SOPA is anti-neutrality. Can you really imagine sites like Wikipedia existing in a post-SOPA universe?
