I have very conflicted feelings about this. Friends who have relationships with wikileaks type people tell me everyone has a duty to use Tor because more Tor users makes Tor more anonymous for everyone.
But there are a couple problems with this. Performance can be terrible, and doing things the wrong way means you are not only not anonymous, but you're actually calling attention to yourself.
Email and the web just weren't really meant for anonymous/secure/private usage, and PGP and Tor are kind of bolted on after the fact, and it feels like it. Messaging apps such as Signal that were designed for privacy from the start fare much better.
