Cant you figure out yourself?
People die with time, people move on
CS is website that manages addons made in the past
Products are there for FSX and P3D
Want them? ok, buy them
Fly them

But CS is not developping new nothing
Utmost a conversion of exterior plane to MSFS

Not until they hire some new dev but even so he would have to start from scratch so why join CS then? If he is good he can do it elswhere.

This website manages registered trade marks of addon planes made in the past. Support for existing addons, forums, payment support, etc

No devs
