I doubt any sort of real revolution would happen, my comment was probably worded badly. I meant more as a turning point for the sort of privacy-conscious people who already use Signal. I, and a lot of the people I talk to, take a position on personal tech privacy on something of a middleground, not the full nuclear option and not the Facebook option. If Signal goes down I would speculate a lot of people who already have things like encrypted messengers, adblockers, things of that nature, would start to move to the only-vpn, no javascript run ever, no Google Play Services on your phone, no proprietary software at any stage of your life sort of deal.
