That is not a good idea.
Let's say that something happens to Retroshare and the software is taken over by a malicious entity, if your automatically updated, your good version will be replaced by the horrible, spying one.
It's best to manually update depending on security updates, while carefully reading through the news.
I also don't want RetroShare to ever give up their morals and convictions. This software is our defense against censorship and the objectification of human beings.
I don't ever want to read about retroshare being bought up by some corporate goons. This software needs to remain in the community.
It can be a valuable tool. If for instance two friends live in different parts of the world, one friend under the umbrella of an oppressive regime, he could securely send video evidence of abuse to his other friend, who could then either share that video with other friends or upload it to youtube or another video site.
Activist groups can have secure meetings and plan protests without being monitored.
By securely connecting to only those you trust, you can make the world a better place. I still that TOR will be needed for web browsing, or other anonymization services but this is that extra layer of protection for communicating with family and friends.
That extra layer of freedom of information. Some people will begin distributing newsletters to their contacts and spreading important information without threat of violence or censorship.
That is why the developers and community need to be vigilant and not get caught up in the moment. It's not the present we should be thinking of, it's the future. And if things continue as is, the future will be very dim.
