It's kind of like a hostage situation when people are unhappy with terms. They won't commit their ideas to the actual project until the demands on both sides can find balance. For some people that balance never comes, but there's obviously a large percentage of people who post here who are unhappy with what's been proposed in exchange for their Bitcoin and won't release their thoughts to Ethereum even though they're interested (therefore holding their energy hostage before spending it on the project constructively).

The delayed fundraiser has put the thought in their minds that the terms may be under review, so they've cooled it a bit. I don't know if that's actually the case, so we wait and see.
