Actually Golos will not be on a sidechain of Steem....it will be on a totally different blockchain. Also if it's good or bad it doesn't really matter, the technology is open source and anyone could try a clone of Steem. They decided to make a clone so they will have to asume the risks of their project.
You cannot clone Steem without violating Steem open source license. cyber•Fund has legal license agreement with Steemit Inc.
I didn't realize that you are on the Golos team. No offense intended...good luck with your project.
That's why they had in agreement with Steemit Inc....but techincally what their doing is a clone.
