I'm also powering down 100% now, and that's not because I'm leaving Steem, it's just because it seems to be the only way to gain a bit of liquidity on the Steem power.

By powering down 100%, once a week I get some freedom of choice, I can choose to revert the power down by powering up, I can choose to sell some steem, I can choose to buy SBD on the internal market and convert it to steem if that seems profitable, and I can choose to channel funds over to other investments.
