Some of these accusations are pretty unfair to you, but in some people's defense, I don't think they're completely unfounded. Unfortunately in the past 2-3 years, you've attached your name to way too many projects (whether or not you were directly involved) and most of these projects have not really amounted to anything. I understand that you've been working hard and have never given up, but at this point it's kind of become your responsibility to prove these accusations wrong and clear your reputation. Hopefully that can be done once Komodo and all these other features are finally released to the public.
It's not his "responsibility" to prove anything to you. Everyone else does not have these concerns. His reputation is fine with everyone but you, and frankly I would rather him work on the code than debate trolls on the internet.
You don't think it's his responsibility to investors, the people who provided funds to help keep his project(s) going?
And you're wrong, there are definitely enough people who has these concerns. Enough to create a reputation.
