Continue doing what has already been set in motion by the fans, as it has shown that it is the best way to get our voices heard considering the amount of noise it already made within just two weeks alone. There is also a new petition to help get the rights back to the creators of the show. I don't know how much that'll do though, but the least we can do is try. I've been involved with fan campaigns before in trying to get something renewed, and while it doesn't always guarantee anything, social media has made it easier to get our voices heard. Look at what the fandom has already accomplished. Netflix might not want to reconsider for whatever reason, but the louder and more persistent we are the more likely someone else might come along to hear us.
So even if it seems like the odds are against us, please don't feel discouraged. When things like this happen, fandom always tends to remain stronger united together. ❤
