Agreed. There was similar discussion around "the free and open web" on this thread some days ago: https://news.ycombinator.com/item?id=45066258

I think some people lose sight of the difference between the theoretical possibility of competing forks/implementations/services and the practical possibility. If a big enough organization gets ahold of something and begins to drive it, the fact that it's nominally open source may not be enough to ensure that people have a practical ability to get out from under that organization. In other words you need not just openness of "information" but actual open space to maneuver in the real world of food and money and markets and so on.

In many cases for-profit companies have taken up (or created) open source tools and made use of them in ways that still benefited the community at large. But it's not clear to me that FOSS licenses as we know them actually guarantee that. It doesn't seem unreasonable to me to want to build safeguards against open source software being weaponized or co-opted for unfree purposes.

One thing that's not clear from the Bearblog dev's post is whether he would be open to small-scale "competitors" who share an ethos similar to his own. In theory such competitors could be granted special license exceptions. If I were in his position I could see myself wanting to exclude big companies (and companies that hope to become big) while allowing small operators. The challenge is to create an enforceable license that encodes that, rather than requiring the author to manually approve or deny each request.
