I think it's more likely to be Demon Hades and his team.
Their JFW-DH cfw was supposed to have been released back in October, then they said it would be delayed by a couple of weeks. Then one month later TB appears, and DH releases a ****ty cfw instead.
Not only that, I believe that zadow showed info that TB uses parts of JFW-DH.
Add that DH said his mother was ill and they needed money.
If you ask me all that info points to DH selling his info to TB or partnering up with them.
