Aerofly FS 4 network data

Hello FS team
You have recently cleaned up the code in version FS4, including changing the names of some functions. But there is no SDK for it.
Since I am developing my own software that uses the API from FS2 in FS4, I kindly ask for confirmation that the tools released for FS2, as well as the license, are still valid for FS4.
The software I am developing retrieves speed, altitude, and other data necessary for recording aerobatic flights of aircraft.

So, licence agreement is the same, yes?

The main task is to record the flight. However, I’m thinking about connecting a joystick with a force feedback system in the future. For now, I’m collecting a lot of data — from speed to reading the angle of inclination, and so on.
That's why I'm asking about the license — because I don't want to break the law, and right now I'm in a gray area. It's kind of okay, but the SDK wasn't released for FS4, so I'm not sure.
In case I want to sell the software, then what? What if a client shows up who wants to pay me for the solution? Am I supposed to tell them it has to be open source?

The main goal of Aero Flight Record is to capture information about the aircraft's position, speed, and external conditions, and to recreate the flight in 3D with a model. I don't send any data to FS4, but I do collect a large amount of data in order to accurately reproduce the flight.

So... what about SDK for FS4?
