I look forward to hearing how the mother who has kids to look after, and already has to work far beyond working hours to satisfy psychotic hiring practices focussing on algorithm knowledge and open source contributions, can then afford more time to do "office hours" with people using the software she has BUILT AND PROVIDED FOR FREE.
I would suggest that you read the article. This is not about locking you down, this is about the benefits of opening a more direct communications channel with your users.
Generally, communication with your users is a good idea, because it gives you insights in how your tools are being used, and gives you a chance to - by asking the right questions - improve your code, and your relationship with the community.
It is about building and applying soft skills.
Your full-time-working, full-time learning, open-source-contributing mother of several children may choose not to do so. Or maybe she can cut some time from the full-time learning and train her people skills, and make her open source product better. Because in the end, a well-run, useful OSS portfolio helps building reputation that is more useful in a hiring situation than deep knowledge about the shortfalls of the Dijkstra algorithm for edge cases.
