Theres a difference between Operation Akumajo and GetMeOffTheMoon/100,000 Strong for Bringing Back Legends 3.
The L3 campaigns are about gaining members and showing Capcom that there IS an audience for the game, that there IS interest, that we want the game, and they made a mistake when they thought there was a "lack of interest" and a "lack of an audience".
To these ends, they are gaining support on facebook, and having people sign up on the North American DevRoom to boost it's numbers as high as possible, Signing a petition topic on Capcom Unity, and leaving a comment on a Legends 3 Cancellation response thread on Capcom Unity, which is reviewed by Capcom's Chris Svenson, Sending mail to Capcom, signing a Japanese poll,
and overall basically just gathering massive numbers to show support.
Operation Akumajo, is basically just a list of demands. "We want this. Give it to us or else.", and encourages members to do the same on Konami's facebook page.
Now, Granted, it doesnt seem like Capcom cares either way, but which one do you think either company is likely to give more notice?
