One of the problems with emulating a PIPA/SOPA protest was each website risked portraying itself as some sort of political advocacy tool. A lot of Wikipedia editors were supporting the day but some also made the point to remain apolitical(as they also suggested for SOPA/PIPA). Which is a fair point because a political/religious stance would discourage editors and readers alike.
Drupal also had the same discussion and through informal consensus decided to run the banner.[1]
I was one of the developers on TDWFB and still wasn't 100% sold to run political movements on cdnjs.com.
The article in question is pretty misleading. There was significant discussion on Reddit[2] and with the help of the admins there was a pretty positive sentiment floating around too(No statistics but I'm guessing they were a huge source of calls, given all the reports on the thread).
The ending quote unintentionally gives credit to the protest I think . Of course everyone knows on-line petitions are a weak form of protest, which is why TDWFB focused very hard on phone calls and did quite well in that regard.
"“Online petitions,” one Reddit user wrote of the protest. “The very least you can do, without doing nothing.”"
So we drove 88k+ completed phone calls, this number does not include the 6k+ phone calls that we couldn't connect because some senators turned off their voice mail(Reddit comments suggest Feinstein was one of them). This would bring the attempted phone calls to just shy of 95k but the tool is still be used today so we hope to hit 100k attempted phone calls. Plus there were a tonne of untracked calls and we hope to get a full number soon.
Our figure on the homepage for emails is semi-misleading. We are actually delivering those emails to 3 reps per zipcode which brings the email count 183k to 549k.
244k international people signed the petition.
Including the day before and the day after, our traffic to the homepage is sitting somewhere over 1 million visitors.
We gained about 350k fb likes and 60k tweets(of the domain) on the 11th.
And according to Cloudfront and my credit card, we served about 1 billion requests. I don't have the numbers on how many times the banner was displayed just yet.
Edit: As pointed out by ronaldx, the article states that DuckDuckGo did not participate, their logo did change and remains so.
Also major thank you to Twilio for sponsoring the calls.
