Why you should give away your work for free... Don't listen. If you make something and want to share it with others, do so. But do it because you want to, not because some blog post guilt trips you into it.
I don't see how the blog guilt trips anyone. I, instead, see very well constructed points on why one should consider contributing to open-source.
Mozilla, famously, open sources all of its code but more importantly dedicates all its trivial code to the public domain. If most competent developers / organization at the very least followed such a line of policy, think of the learning that could entail, technological advances that could be turbo-charged, all the duplicated work that could be avoided.
This isn't a hot-take by any measure. Examples of enormous impact of FOSS are right in front of us: More developers doing so only adds to this amazing ecosystem.
The blog post gives examples of how one can benefit from contributing to open source projects, e.g. "You can learn a lot from the source code" and "it can be very rewarding to see your own code helping so many people."
