Alright so a lot of people are worried about the eclipse update (myself included), but at the very least there are things you can do to try and help get DA's attention about the whole thing.
You can sign this Petition, basically saying that you aren't happy and don't want eclipse to be forced on you.
You can tell them directly here what you think of Eclipse (I highly suggest letting them know if you'll be stopping your core membership if the eclipse update goes through, they hold money pretty high up, and if the money stops coming in they'll have to listen to us)
And you can take part in #thesoundofsilencemovement , more info can be found
