No, Construct 2 forums are not dead. lol
It's just been slow the last couple of weeks probably because spring brake is going on, and all the young members are in some tropical paradise right now drinking up all there parents hard earned money.
Also, there are a lot of members lurking in the background see all the guests on line. I bet most of them are members of the community just waiting for some awesome announcement like audio now 100% working in CocoonJS, or in app purchases now working in CocoonJS. LOL
Stick around things will liven up.
