Their track record when confronted by people who have issues with some/all of the above is not encouraging. They appear to me to be putting far too much faith in "we're doing BitCoin on the internet" as a magic shield against laws, and they do not appear to have ever talked to anyone who knows even the tax or service laws of even major countries in which the developers they solicit on "behalf" of live (evidenced by comments from them that they are too small to afford lawyers).
