How does the existence of Electron decrease the ability to use other tools? It only offers another option... Just like .Net/Java do, both of which have disadvantages over C/C++ and the like.
What it comes down to in the end is, is the trade off worth it. With Electron/PhoneGap and the like, you have a much faster path towards an application. Web tooling is broadly understood, and a lot of that logic/workload can and often is already done, and being able to reuse it is helpful... Having a stack that is closer to the rest that you are using anyways means less disconnect.
It's not for everyone, but in the end it doesn't stop anyone from using C++, Go, Java, C#, Python or a number of other languages/tools.
