The real reason for free downvotes in the last hardfork: FREE CENSORSHIP

Whales defending this new downvoting-bidbot-customers policy do so because it is profitable for them.

Non-whales were liquidating too much value out of this blockchain's economic value, which is not bad according to the offer/demand market, but sucks to old higher-profile inverstors who want to milk more easy money out of the system.

Truth is, this policy won't change anything except make good authors more prone to leaving steem altogether because of the growing number of competitors that might offer better pay.
