The EOS blockchain doesn't even exist yet. How can they sell a token to be used on a chain that doesn't exist? They will be redeemed for EOS tokens. Read actual publications by EOS to understand these things. Go to the source.
I'll watch this video, but the way you describe it, it sounds like FUD. Almost every ICO terms of service I've seen has similar language basically saying you're donating to them and you get nothing in return which keeps them out of trouble from the government. It's all about trust. If you trust a project team and their vision, you invest, otherwise you don't. For those unwilling to do that, they should wait until the project is fully functional and launches and buy the tokens on the open market.
