Just pointing out that in no way was I saying I don't trust the Carbonite developers. I was talking about why many many other commercial products are open source.
TBH, if you believe that you can trust a closed source vendor with making highly secure products you have never used a Microsoft OS. I work for a company who does network security products. If it weren't for Microsoft we'd be out of totally business
At any rate, it is no biggy if they don't make Carbonite open source. I was just pointing out that being open is perfectly viable for commercial software.
Sorry you missed the entire point of my post.
