Steemit Inc needs to outline a bill of rights, a manifesto, or something so that there is some predictability for these sorts of changes. If there is some set of rules for when the economics can be changed and only when it meets certain criteria then the community can accept it. It's hard to accept it when it looks completely arbitrary or when it's done merely because one group of people feel like it and voted to do it over the interest of the minority group.

+1. A constitution could help guide behavior in situations of suggested change. It would also help manage situations in which tragedy (hacks) occur. Ultimately, blockchains are here to support communities. I'd suggest a Steem constitution reflect that.
