How about Charlie Lee, the creator of Litecoin? How many Litecoins does he have? Will he be put into jail or have to hide somewhere? Do people avoid using the official Litecoin client because Charlie is not anonymous?
It's kind of apples & oranges. Satoshi's invention was monumental and revolutionary. Litecoin, while I don't mean to belittle it (and I do own some), is an incremental and not even necessarily superier alternative. The market cap of Litecoin is dwarfed by Bitcoin, and it receives orders of magnitudes less media coverage.
If Charlie Lee went around smoking crack cocaine in public (or snorting... or injecting... Idunno - whatever they do with that) - and again, I don't mean to belittle LTC or Charlie - nobody in the media would care. It wouldn't justify running a story and it'd probably have no impact on Bitcoin. If Satoshi came out of the woodworks and bought a bunch of cocaine off whatever the current Silk Road is, then made it public - it'd be run all over the press as something to laugh about. It'd get ratings and, by association, discredit something threatening the current power structure. Litecoin would likely lose credibility if Satoshi came out as some type of backwoods hick with paranoid schizophrenia, but Bitcoin wouldn't lose credibility if the same were known of Charlie Lee.
Bitcoin is a completely open source project and everyone can see the source code.
Since someone already mentioned about Linus, let's talk about Linus. Linus is obviously not a polite person and always being very rude in the community. Do people refuse using Linux because of that? Einstein as another example, as we know actually he was very mean to his wife, do people care about that? I don't think we should evaluate an innovation by looking at the personality or even dignity of the inventor.
Most early adaptors are convinced by the white paper and open sourced project, and the current adaptors are mostly attracted by the 100x appreciation. Nobody really cares who Satoshi is and whether he's a good guy or bad guy. Now Gavin is the one who works at the official client full time, does anyone care about Gavin is not anonymous and who have paid enough attention to ensure Gavin is a good guy who will not put some malicious code inside? No, because it is open source project.
The only impact of Satoshi is that whether and when he will sell his holding. If he is anonymous, that's the only meaningful question for people to ask them and apparently will not get any reliable answer.
I've never even heard of a Linus, but I don't fully disagree with you. The issue I kind of have is that you can easily say Satoshi was/is a peddler. That is, if you buy or otherwise support his coin, you're effectively handing some portion of that money you used over to him which he'll take when he dumps (should you assume he's going to sell). If you spin the story as some guy who goes around peddling this coin of his, it looks a little iffy, especially if he's a "bad" person. Should it've come out that Satoshi was/is a child-raping terrorist who murders puppies, I don't think many people would want to support anything created by him on principle, for the same reason there are many who truly believe inhumane research should be ignored -- research from Nazi research on jews, gays, etc. -- but in this case, you're not only embracing the "fruit" of the person, but also potentially giving the person money.
I'm looking at this in a worst-case scenario light. Let's say there's a local shop in a fairly small community, and the owner is a convicted child rapist who allegedly sold child porn he made to buy the large house he lives in. He offers disruptively low prices, though. Do you buy from him because he apparently has good ideas, or do you refuse based on principle and because any profits the shopkeeper holds may be used to sustain a morally reprehensible lifestyle? Maybe another member of his family runs it, but there's still going to be a moral dilemna there, and I think it's reasonable to assume a good few people will refuse to shop there.
Put yet another way... I used to be fairly active in libertarian circles. They would literally start blanket "embargos" (what's the word I'm looking for? Consumer strikes?) on companies owned by a company or person they have moral qualms with. Is the effect significant? Maybe... probably not... but it's not something frequently in the press. There are some particularly horrible companies like Monsanto, and even though there's a fair amount of coverage in alternative press, it's still rarely covered in mainstream press, and I doubt most people have a negative opinion of them or even know what they sell. If their misdeeds were covered in the mainstream press, I think it'd be a different story, though maybe they'd still be profitable and take in close to the same amount of revenues. Given Bitcoin is relatively ideological and tends to attract a fair number of ideological people, I think there would be impact from Satoshi revealing himself and possibly being dragged through the mud by unsavory people in power. Did Satoshi take the same line of thinking, or did he have something else in mind? Obviously, I have no idea.
