I've found that layoffs and RTO have multiplied the toxicity of development communities. People will openly threaten to call your HR department if you say something wrong. Developers and engineers aren't trying to get better, they're just harming each other in a loop until the most evil one survives. It's cut-throat but not even in a good way, just extremely anti-social and aggressive.

I don't recommend any development communities. If you want to try Discord, many people who will try to get you fired are available to chat with. I talk with long time friends who are developers but it's mainly really sad conversations.
