Nothing. Except Thunderbird+Enigmail is not something that is going to appeal to the masses. Web-based mail came along and all of a sudden it didn't matter where you were in the world, you could log in and check your email from any computer. Encryption means nothing unless both parties are using using it (obviously), and if it's only a few users who are encrypting emails using Thunderbird+Enigmail then there's that "why are you encrypting, you must have something to hide" and so the theory goes that you are more likely to catch the eye of big brother who then keeps a closer eye on you... if everyone is encrypting everything then we are all on the same footing. Unfortunately things need to be made easy for the masses to adopt, like the way iMessages works, which is seemless. I don't want to worry about which pgp server upload my key, or having to go to 10 different places to revoke my key. BUT, I don't trust any web-based encryption either since it's liable to be tampered with: https://en.wikipedia.org/wiki/Hushmail https://en.wikipedia.org/wiki/Hushmail Thunderbird+Enigmail is the safer way to go in general (and is actually what i use also).
