You are not entitled to define what Open Source is for me.
To truly transcend in programming or any other discipline, we must first conquer ourselves. Which might mean letting go of expectation, especially from others. If bug and feature requests are piling up to the point that they distract from the work, then maybe their piling up has value. Being mindful of that doesn't mean solving it. It could be more about delegation, or communication, or setting boundaries, or any number of things.
I sympathize with him tremendously though. I don't even have a public body of work to showcase, or a way that leads to fame or fortune. Yet I still feel tremendous pressure to perform some days. His post doesn't read too terribly in the face of that kind of pressure.
Of course it was written by attorneys. Do you know how FSF, DFSG and OSD even began? They found a legal solution to the problem of sharing code while guaranteeing certain rights for the user who use the code! The open source licenses are written by attorneys too.
You are free to distribute under whatever terms you want but your code does not become open source just because it is shared with the public. Some countries do not even recognise "public domain". In such countries it becomes necessary to attach a valid open source license to your code. That's why the various open source licenses are drafted by attorneys to ensure they can provide appropriate rights to the user of the code.
