That's a slightly different scenario. If your product was written in C and your boss was disappointed that it couldn't saturate a 40Gbps link, a well—written and commented implementation (in C) that could would probably not be rejected.
As others have pointed out, a lot of your failures sound more political than technical. Dealing with idiots and jumping through political hoops to get them to go along with an idea that they didn't think up themselves can be extremely tiring. I cannot claim any particular expertise in that area myself, and I can't think of any way around it (aside from working alone, of course). I figure cooperation is the cost of progress.
