Since my previous attempt, to ask this question was closed for not being "focused" enough. Please focus your attention on only this:
How private is the code you write in Visual Studio code? Specifically, does any outside resource see the code you've written in Visual Studio code?
For example, Visual Studio has a lot of features that aid you in writing code. Are all those features locally self-sufficient, or does Visual Studio Code upload your code to cloud resources in order to facilitate some of those features?
If Visual Studio Code uploads your code to do processing, I'd consider that a violation of my privacy. I do not use Visual Studio code yet and this is a legitimate concern of mine before starting to use it.
