I wasn't doubting their software until 1) I couldn't reproduce their build, 2) I realized they don't have their issues tracker enabled, and 3) I saw their toxic attitude and actions taken towards it's users. Those a three very big red flags for me and are enough to not trust them.

So is their software bad now? I don't think so but at the same time, how would one know without a public issue tracker and with how they react when issues are found and pointed out. These two combined lead me to believe that there is the potential for issues or bugs to be present that some may have found but have no way of publicly reporting and/or are blocked and/or threatened with lawsuits by Coinkite themselves if the person finding the issue speaks out.

The alternative to CC that I've found so far is Foundation's Passport2. They have been a stark contrast to CC in terms of being extremely transparent, receptive to feedback and issue reporting, and have probably the BEST reproducibility documentation out there. So far they seem to be doing all the right things.
