In fact, the petition's purpose is now to open an official Vanilla (Legacy) server. Nostalrius will not come back.
If you have a twitter account, retweet everything about the petition. If you dont have an account, create one

Why? Refer to my initial statement but replace "reverse C&D" with "Open a Blizzard server". Although I don't know why anyone would want Blizzard to open a server as opposed to allowing Nostalrius 2.0. Seems pretty stupid knowing Blizzard won't do it right and probably charge money for it. Especially since they don't deserve to be paid any more than they already have for vanilla. And Blizzard server is even less likely due to the potential losses compared to allowing a private server to run. So that reduces the effectiveness of the petition even more, assuming it was even effective to begin with.
Will we ever learn that begging an enemy doesn't work? Probably not because alot of people are morons that support things like socialism without even knowing it, like trump supporters. Not that other candidates are any better. And I know there's plenty of smart people, but its a realistic observation based on history and the behavior of the general population. Youtube cringe compilations is a perfect example. Although alot of it is based on diet because junk food literally makes us idiots.
I've said it before, but if Blizzard opens a legacy server, it will be based on a decision they already made regardless of whether or not we have an extra 50k signatures.
