well I didn't investigate who is/are the owners of block.one but Dan being the key figure and face of the project presumably is involved in that company too. Another thing is that purchasing the tokens do not give you any rights/shares etc. according to the purchase agreement:

1.4. EOS Tokens.
No Purpose. As mentioned above, the EOS Tokens do not have any rights, uses, purpose, attributes, functionalities or features, express or implied. Although EOS Tokens may be tradable, they are not an investment, currency, security, commodity, a swap on a currency, security or commodity or any other kind of financial instrument.

So basically what they say is we will get 2 billion USD and you can trade the tokens hoping that their value will rise but they are not in any other way useful or connected to the project itself. The project may or may not be launched and so on... So basically we (people who are willing to purchase the tokens) are funding a 2 billion+ USD project which we can't benefit from in any way other than hoping that the value of the token will rise which may not since you can't use the tokens to purchase future ICOs developed on EOS blockchain which is the case with Ether. Someone please correct me if I'm wrong. Of course there is good chance that the project itself will be a great success and EOS tokens value will rise but being informed at the beginning that the tokens are essentially useless and they have no purpose other than rising money for block.one doesn't make me feel very generous towards it.

Sounds like just another shady scam by a bunch of shady nerds, just like steemit (let a few insiders in first, let insiders build power/influence/vests, then let the general public in so those same few insiders can use and abuse the noobies for their own profit/gain while convincing said noobies they are part of something special that may make them rich some day)....
No thanks. I think I'd rather risk any potential investments I may make with the upcoming independent steem fork (free from Stinc) called Calibrae (launching in about a month and a half, proposed and designed by @l0k1 / @elfspice).
