>They are normalizing the "workaround" of using an insecure IP address when Tor is inaccessible. This will lead to all non-secretive and non-illicit Tor usage to go back to the open insecure internet. Thus, everyone still using Tor "has something to hide" (as if that wasn't the case already). By forcing all but the most desperate users off Tor, Tor can be discredited as a nefarious tool.
I think this is a reach - after all, if you wanted to discredit a tool for people in oppressive regimes, people who care about their privacy, and people doing illegal things, why start with the programming help site? (I know SE has other sites, but the biggest ones are for tech help)
...That said, I could see this being a way LE could try and unmask a very high-value darkweb programmer. Still a reach.
