Yes you have. You have promoted Cryptonote, Bytecoin, Monero, Bitcoin and your CoinJoin service.
CoinJoin isn't a service, ... I guess you've pretty conclusively shown you have no clue what you're talking about.
Nor have I promoted Bitcoin here I haven't said anything positive about it at all. WRT the Bytecoin & forks I don't really believe that I'm promoting them, they suck in a number of ways unrelated to their privacy features, and the decision to make an altcoin out of it seems shameful and greedy to me... but the privacy part is really quite brilliant, and thats just my opinion as someone who has been working on privacy in this space for a long time.
Doesn't Gmaxwell own large amounts of cryptonote coins he's trying to hype
Nope. I have a bit so I could try them out, and some people have made use of my monero tip address, but its all trivial amounts. I think altcoins are generally inadvisable, and in the long term I have plans that should remove all reasons for having them. I think the promotion or opposition to these things based on profit motives is incredibly sleazy.
Darksend in its current state is more advanced than the coinjoin on which it is based
I've seen no concrete evidence to support this. Can you point me to some? I'd certantly be happy to find that I was incorrect, I think privacy technology is interesting and important and while I think creating an 'altcoin' for it is counterproductive (immediate loss of anonymity set) and pointless, if something good is developed I'd welcome it. But after sitting quietly for some time the indications that darkcoin is largely substance-less vaporware and hype have grown stronger, not weaker.
