I don't agree with the premise that people will be contributing back to the open source software they use. Most consumers of Typescript for example, would be unable to contribute to the core codebase, the same goes for Rails, Redux, React, etc. The actual percentage of consumers vs contributors I would reckon at less than 0.01%, possibly lower. As a developer looking for a job, I would use GitHub to build a small project end-to-end to demonstrate competency, but that's just me and the slice of the programmer world I live in.
