"Technologies like objective C, C sharp, Azure or swift are designed so you can not escape the company platform. So easy to get in, so hard to move your code to other platforms once you have been programming for years on them."

FYI, Swift is available on Linux and Windows along with a significant chunk of its core libraries (e.g. https://github.com/apple/swift-corelibs-foundation) and app frameworks such as Vapor (used for writing web apps and APIs).

C# is also cross-platform. .NET Framework has been completely replaced with .NET Core now (and renamed to simply .NET).

The only part of cross-platform support that's a little wonky is the GUI, but that's because Forms is just a thin wrapper over the Win32 forms API and WPF was built around DirectX. But that should get a lot better in a couple months when Microsoft releases MAUI (Multi-Platform App UI).
