I feel like there's less incentive to pay as a gold member now. The game report was great–recommending lessons, showing lines that explained why your move was good or bad. I feel like I've lost a huge amount of analytical functionality now and I'm still paying the same price. It's really frustrating that this new feature seems like it's just an excuse to hide some of the perks of the game report behind an even bigger paywall. Maybe it's way better but a lot of players including myself are never gonna know because we don't want to pay for an even more expensive plan. It really just feels like people who are not paying for the top tier membership just got robbed of a feature that they've always had access to. And yeah, you can toggle between the analysis and game report tabs, but what's the genuine benefit of making it more of a pain to find out why a move you made was bad? This feels like a purely for-profit decision and really makes me feel disrespected as a paying member of the site.
Yeah big agree here. Feels pretty bad to consider Gold or Platinum at any point, but I'm not going to pay double just for this feature. I'll let my membership lapse at end of period and head back to Lichess I reckon.
Also I am seriously looking at Decodechess which has improved since I last looked at it. Furthermore Decodechess can be had right now for $44 a year which seems like quite a bargain. Since my Chess.com Gold expires in a few months, if the constant noise to upgrade to Diamond does not go away, I will go away.... 
Go to "Home" and it's a big banner at the top, IF you are a diamond member.
Also, you have to play a game now (since it's new) to use it afterward.
You can run it on any old unanalyzed games. I also believe going into a previous analysis will rerun with the new code.
