But why? Person spends his time making useful thing, and decides to share it freely. Like, thanks! But you should also register a trademark, and monitor domain registrations and search engines and other projects and proactively issue takedown requests and litigate your trademark use. It is so irresponsible if you don't, because it may be confusing for some of the people using for free the thing you make.

Like, the only logical outcome I see is hobbyists pulling their projects.
