"Get your name on the sponsors page of our website"
I got a little chuckle at the irony in that.
You take 2 envelopes. Write the word UP and DOWN on two separate pieces of paper, mix them up and put them in an envelope. Send them to two different locations. Open one envelope and you will have the opposite reading in the other envelope which could be miles or light years away. As far as transmitting data this is more inline with what is happening.

Certainly this software has caused all kinds of difficulties with some government organizations being able to get to encrypted data they have confiscated/accessed. Those government organizations certainly want people to use something that has a backdoor in it. It has already been shown that the government has compromised other encryption schemes... what makes you think they have stopped doing that?
It is possible some organization (government controlled) pushed them to close down. XP support ending just gave them at least some reason why to do so. By posting what they did on the website even if Trucrypt is resurrected it will always have this stain in it's history where the developers have stated it is not secure. No company is going to want to use this software after a warning like that from the developers.
