Even if it's not his fault the maintainer at this point won't be trusted at all. I feel for him, I think even finding a job at this moment for him would be impossible. Why would you hire someone that could be suspected for that?
No. From what I've read on the openwall and lkml mailing lists (so generally people who know a lot more about these things than I do), nobody accused Lasse Collins, the original maintainer, of being involved in this, at all, and there wasn't any notion of him becoming untrustworthy.
This could've happened to anybody, frankly. The attacker was advanced and persistent. I cannot help but feel sympathetic for the original maintainer here.
