And? People are welcome not to write OSS if it’s a burden.
1) the top 1% employees in the field who have the luxury to invest unpaid time, and the social clout to make their projects more successful, or to join more successful projects. (example: how much more likely are you to be a key contributor to Kubernetes if you are, or were at some point, employed by Google?);
2) the other 99% who cannot afford to invest the spare time, and do not benefit from the social proximity to successful open-source contributors (and success in open-source is as much about social proximity today than technical skills, hopefully we can change that in the future);
3) The corporations who benefit financially from open-source, sometimes enormously, with very little pressure to contribute back because of the aforementioned social pressure on individuals to contribute on their free time. The expectations are so low that even modest corporate contributions (joining or starting a foundation, hiring a few engineers, paying for a conference) will be hailed as generous and benevolent, because the bar is so incredibly low.
Is it really? Of the people I know who have had excellent career paths in software/computing none have a track record of open source contributions.
Right, that’s how they built their career in the past. All things being equal, it will become gradually harder to build a career that way in the future. I already know several major employers who look at a candidate’s github activity as a factor in the standard hiring process. And that trend is only accelerating.
If these people spend a lot of their free time, and perhaps even some of their professional time, in Github contributing to various public projects, then they might not necessarily have 100% focus on the employer's tasks. I am not sure if this is what the employers expect or even want to happen.
The intention is probably to use Github activity as a pre-screening proxy metric for technical capability and skillset. But... why would someone who is contributing a lot to public projects cease to do so, once employed? Is there a risk of getting a partially distracted, though skilled person?
If the wish from the company then is to ensure they get the most performance for themselves, the logical step would be to cut down on the public contributions via e.g. legal and contractual means.
So... why would someone who enjoys contributing to public projects join a company that selects based on Github activity, if it is in the company's interests that further contributions should be reduced?
Ahh... Maybe I am just overanalyzing it.
EDIT: people or corporations, same thing.
