Yeah same! I've been panicking the last couple of days but I do think I understand now. It is better for the Steem brand, with the original logo, to be kept for the Steem blockchain.

If you think of it like Chess, Steemit is the Queen and the most valuable piece, but it is still just one piece. Encouraging an ecosystem of lots of other pieces to grow up around the King, which is the Steem blockchain, and playing with all of those pieces together, is what will make this project stronger in the end, and I think that's what they're doing.

I was really against it, but now I do support the change!
