I suggest that you post this to the bitcoin-dev mailing list. More people are likely to see it if you do that, and you may get some comments.
Yes, most of us have left due to the censorship of Theymos-controlled fora.
It really has nothing to do with censorship but rather the fact that it is hard to have discussions on a forum and there's a lot of spam and garbage here. Technical discussion left this forum long before censorship became a supposed problem.
Development and tech talk is now mostly scattered across various Slack channels, such as btcchat, btc1, bitcoinunlimited and bitcoincore. Let me know if you'd like an invite to BU slack.
Bitcoin Core does not use slack as slack is a closed community that requires invites in order to join and communicate. We prefer open channels of communication such as mailing lists and IRC where anyone can join without need for invite or prior approval.
